My shop is in my basement, which has always seemed to be a very dry
floor. However, about 4% of my cords, my spare radio and tv knobs,
and the handles of my tools get a think layer of some sort of mold on
them. It's like a grey dust. (Or some other light color, I forget.)

I wasg them in the dishwasher and they come out clean, but once in the
basement again, after a few months, U notice that the same ones have
mold. And the rest never get mold.

I suppose I could just ignore this, since it doesn't spread, but I
wonder if any of you have ideas. No other part of my house is neat
or clean, but the shop is the most important place, and I'd like it to
be clean.

Thanks.

So what are your lungs like?
Wasn't the biblical plague of deaths of the first-born sons put down to the
premium food reserved for the first-born sons, stored in the basement, being
contaminated with ergot or some-such mold

That's one theory, as made popular by a TV documentary.
http://en.wikipedia.org/wiki/The_Exodus_Decoded
The problem is that ergot can cause death in sufficient quantities,
but more commonly causes hallucinations, temporary insanity,
convulsions, and various symptoms that look like madness.
http://en.wikipedia.org/wiki/Ergotism
None of those symptoms were mentioned in the Old Testament. If it
were a massive overdose of ergot poisoning on the surface of the food
storage pot, there would be enough at lower levels to create mass
insanity. Ergot is also very easily visible in unmilled grain, and
would have been recognized. Also, the Nile valley is a large area,
with diverse microclimates. Chances of a country wide epidemic of
ergot poisoning is unlikely.



Drivel: Short lesson in critical thinking... If you read something
that looks like cause and effect, try to visualize what else the cause
might have produced. In this case, what would lesser concentrations
of ergot poisoning produce. There are plenty of theories that will
fall apart after failing that test including government solutions and
creative economics.

Hope you wear some kind of protection when you're in your basement.
This doesn't sound good to me over time for your lungs, etc... .

Probably need more information about the basement such as what's done
there, does this occur only in one area or all over, humidity level,
etc... . You said the rest of the house is not clean so I wonder if
there is a connection to the basement?

I wash them in the dishwasher and they come out clean,
but once in the basement again, after a few months,
you notice that the same ones have mold. And the rest
never get mold.

I'm wondering whether it's plasticizer migrating to the surface.

You might try putting the "susceptible" items in plastic bags and sealing them
tightly. I wouldn't be surprised if the "mold" continues to form.

So you mean clean them first and then do this? OKay, I'll try it.
It will take a few days at least to start the test and up to a month
or three to wait for resutls, but I'll get back to you. At least I
sincerely plan to.

Thanks to both of you and all of you.

Probably need more information about the basement such as what's done
there,

Welll, sometimes I just watch TV, sometimes I make a fire in the
fireplace, most of the time I work on electric projects in the
"family" room and wood or metal projects in the laundry room, fright
next to it.

does this occur only in one area or all over,

I think it's all over the basement, but I guess there are only 2 or 3
areas where those three things are kept. There is a dresser at the
far side of the room, the back end of the house. I keep a lot of
knobs in one of the drawers -- knobs that go back to the 1930's but
mostly I think it's those from the 50's and 60's that get moldy -- and
4 or 5% get "moldy". I put it in quotes this time because I've been
assuming it's mold. It's some sort of dust like stuff, that I can
wipe off with my fingers, but I use the dishwasher because it gets
into the cracks and crevices. .

There is t he pair of little dressers that hold my work bench, in the
middle of the house, near the base of the stairs. That has tools in
one of the drawers and in the In-basket at the far end, plus some
bananan plug jumper wires that get moldy. Thiese 8" jumpers were two
of the few cords that got moldy. Mostly it's knobs and tools. .
(Tools with yellow plastic handles are some of the moldy handles, but
not every yellow plastic handle.)

And about 18 months ago I set up the new computer in the basement so I
could use it to fix the old computer (which needed a new cpu.). So I
do that stuff down here too.

humidity level,

I think the humidity is about 30% in the summer. Lower now. (I"ll
get a meter and measure it , sicne you ask) But I'll say this. WRT
water spilled on the laundry room floor, some of it soaks into the
cement quickly and the rest evaportates within 12 to 24 hours (even
when there is a lot of water from the laundry sink over flowing, or
the hose to the washing machine springing a leak) and the cement
itself dries out in less than 12 hours. I used to make a point of
taking the laudry upstairs as soon as it was done, but one time I
forgot and since then I've noticed that it can sit in the washing
machine wet, for days, without getting moldy or smellilng bad, and can
alos sit in the dryer only partly dried for days and it smells just
the way freshly dried laundry should smell.

20 years ago after one of the bigger leaks, some mold grew on a
sheetrocked wall, but I killed it with bleach and then painted it
over, and that was the end of that.

etc... . You said the rest of the house is not clean so I wonder if
there is a connection to the basement?

I was mostly making a joke. The rest of the house isn't that dirty,
and anyhow, it was clean for 15 or 20 years and I still had the moldy
cords, tools, and knobs in the basement. Two or three times I've
gathered them together and washed them in the washing machine. I
don't pay close attention, but they all turn moldy again, in less than
a year, probably less than 3 months.

I'm not worried about my health. Some mold is bad for all of the
people some of the time, and some for some of the people all of the
time , and some doesn't bother some people any of the time, and
whatever I've got here has never bothered me in the 30 years I've
lived here. And I'm the only one living here now. I'm just
getting tired of having moldy things.

I used to think like you ... that my body was pretty strong (and it
was) but lately I'm experiencing things that never used to be so I
think age is the culprit. My point is that even if your body was
strong against the mold before, it may change with your age now. And
it may be too late after you begin to notice it. Sorry if I seem
overly concerned but I've had to deal with Cancer patients going to
the doctor, etc... .

I also have a parts drawer with an assortment of old knobs and I
recently had the same experience you have. Out of an assortment of
about 25 there were 6 that had an off white coating similar to mold.
The coated knobs were identical and appeared to come off the same
piece of old test equipment. The rest of the knobs were perfectly
normal. Thinking they were moldy I soaked them overnight in a clorox
solution and it didn't phase them. So it definitely wasn't mold. But
with soapy water and a old toothbrush they cleaned easily so I
determined it was an old plastic compound reaction.

Contrary to what some are saying I don't think you have a health
problem in your dry basement.

Some Craftsman tools with plastic handles left in a car trunk or hot
toolbox for a long time often get real stinky. That again is the type
plastic they use and giving them a soapy bath usually helps a lot.

That's exactly my experience.
http://www5.picturepush.com/photo/a/...g/12297573.jpg

The plastic on the handles was coated with a thin white layer
which I could scrape off with a sharp tool (the results in
that picture are of a screwdriver scraped years ago, but some
of the persistent white stuff is still on the handle, in spots).

I don't know WHAT it is!

Like you experienced, it wouldn't 'wash' off and chlorine bleach
didn't faze it (of course, if it 'is' mold, it would be dead but
still there if bleach did kill it, since it's white).

I don't know if it's a "mold" or a "chemical".
It does seem to 'infect' other tools - but both a mold and a chemical
'can' do that (think hydrochloric acid).

The coated knobs were identical and appeared to come off the same

solution and it didn't phase them. So it definitely wasn't mold. But
with soapy water and a old toothbrush they cleaned easily so I
determined it was an old plastic compound reaction.

That's exactly my experience.

The plastic on the handles was coated with a thin white layer
which I could scrape off with a sharp tool (the results in
that picture are of a screwdriver scraped years ago, but some
of the persistent white stuff is still on the handle, in spots).

I don't know WHAT it is!

I have some hard spots on my tool handles like that, but I know what it is.
It is remnants of paint that may have been on my hands when I used the
tool while painting, like removing face plates off switches and outlets,
or other uses of the tool while painting.



Like you experienced, it wouldn't 'wash' off and chlorine bleach
didn't faze it (of course, if it 'is' mold, it would be dead but
still there if bleach did kill it, since it's white).

I don't know if it's a "mold" or a "chemical".
It does seem to 'infect' other tools - but both a mold and a chemical
'can' do that (think hydrochloric acid).

I wasg them in the dishwasher and they come out clean, but once in the
basement again, after a few months, U notice that the same ones have
mold. And the rest never get mold.

I suppose I could just ignore this, since it doesn't spread, but I

The plastic in some tool handles will break down over a period of time. It
is just bad quality plastic. Even some other wise good tools have this
problem.
If it only some tools and always the same ones, you just have to replace the
tools when the handles fall off.

Just use that dipping handle cover.
Here's one such product
http://www.plastidip.com/home_solutions/Plasti_Dip
I have different tool boxes for different uses, such as electrical,
plumbing, carpentry, car, bicycle, motorbike, general, etc.
I get it in different colors, to identify which tool box or "application"
tool kit they belong to. It has really cut down on tool "evaporation". It
also has made enforcement of tool replacement to it's proper box far easier
with other family members.

What kind of handles do these tools have? Steel, plastic, rubber, wood?
You say these things have a 'dust like' layer. Could it be brushed off,
or has to be washed off in a dishwasher?
I know many of my tool handles get a gray or dark covering after a
while, but I attribute it to an accumulation of dead skin cells from my
hands.
This could also be attributed to the handling of the TV knobs.
I don't know about the 'mold' on the cords.
All my tools are in an attached garage.
I doubt whether this is mold if there is no other mold in the basement.

Try to store it in a plastic bag together with a package desiccant
(Silica gel).

It's not mold. It appears to be mold, but if you look carefully, it
doesn't "grow" in a radial pattern, as you would expect real mold to
grow. I've put the dust under a microscope to be sure. It's plastic
dust. Hit is with some heat, and watch it melt. I get this plastic
"mold" on most of my cheap plastic handle tools. The plastic breaks
down along the surface and sorta crumbles. It's probably caused by
exposure to something in the air, which condenses onto the surface
when wet. Washing the stuff off with any kind of kitchen cleaner
works, for a while.

I've tried a few things to prevent its return. Dipping or spraying
with acrylic coating (clear Krylon) seems to work best. I have one
old plastic handle nut wrench, that I coated only half with acrylic
spray. I can see tiny pits starting on the uncoated side, but the
coated side looks like new. Note that you have to really clean the
plastic with sandpaper and solvent before spraying or it will flake
off. Also, don't worry about the dull finish after sandpapering, as
the clear acrylic will make it shine again. Also, the acrylic
sometimes feels kinda "sticky". I'm not sure what causes that.

Unfortunately, I haven't had any luck preserving rubber and flexible
handles that have the same problem. The acrylic coating just cracks
and falls off. Even worse, I haven't found a fix for the rubberized
paint coating on plastic, that eventually turns to a sticky gooey tar
mess.

You can eliminate UV from the guess list. I've had it happen in a
closed toolbox, where no light enters except perhaps twice a year.
It's also happening in my steel drawer tool boxes, where again little
light enters. Ozone is a possibility, but I don't have any obvious
sources for excessive ozone in the shop (Hi-V, electrostatic
precipitators, negative ion generators, laser printers, etc). However,
I do store aromatic chemicals nearby, which may be the problem.

Also, an important clue is that I can have a drawer full of plastic
handle hex spintite wrenches, and only some of them will have a "mold"
problem. This implies that the culprit is resident mostly in the
plastic and not the environment.

This is a drawer from my steel Craftsman toolbox that I don't use very
often. The white stuff is the alleged "mold". Note that it's on two
of the handles, but not the others. The larger tools are made by
Vaco. The blue and the yellow handles are covered with the stuff.
However, the other handles, from the same manufacturer, are pitted,
but untouched. That's because they previously were cleaned and coated
with a very thin layer of Krylon clear acrylic. I'm not sure why the
blue and yellow handles are affected. I probably just forgot to coat
them (about 18 months ago). There is no rust anywhere inside the
toolbox on any of the other tools, so it's not moisture accumulation
or consensation.

That's EXACTLY what this screwdriver USED to look like!
http://www5.picturepush.com/photo/a/...g/12297573.jpg

So, whatever it is, it's common.

Again, I don't know if it is a mold or a chemical.
It does NOT happen to all tools of the same type.

It just happens to select tools which were stored in a
different environment (I think my affected screwdrivers
were used when I worked at a hospital on oxygen respirators).

Yes, the yellow one has the most. I t hink my yellow ones are most
likely to have this and when they do, they have the most. The one
screwdriver that reminded me of this has a yellow plastic handle.
(The other two things t hat reminded me a couple days ago where jumper
wires with banana plugs, blue and green, but that's soft vinyl and not
hard plastic. ......))

Your explanation makes more semse than "mold". The OP did not say
what type of handles or tools were/were not affected, or if the tools
were in a dark airless corner or out in plain sight, etc, so we really
need more information.

Wow. The real Jeff Liebermann (two n's and i-before-e) on alt.home.repair.

I'm impressed. You're the expert in the SC mountains for wireless radio.
Glad to have you here.

I am VERY FAMILIAR with this persistent "white stuff".
I have no idea WHAT it is - but I have it too.

It's either a chemical coating or it's a mold-like growth.
It does seem to be hugely persistent, in that if you don't scrape it
away, it will last (seemingly unchanged) forever.

I remember segregating my white-coated tools a while ago, but I no
longer do that once I manually scraped them (mostly) clean.

I seem to remember that the white stuff "infected" other tools, but,
it's no longer doing that (after twenty years). But, that white stuff
you see in this photo is easily twenty years old!
http://www5.picturepush.com/photo/a/...g/12297573.jpg

It had coated that screwdriver handle with a white persistent but
powdery on the outside surface coating just like the picture the OP
posted over he
http://802.11junk.com/jeffl/pics/drivel/plastic-rot.jpg

I considered throwing the screwdrivers away, but, my sense of
tool preservation had me soak that screwdriver maybe 15 years ago
in all sorts of horrid solvents (acetone, bleach, acid, etc.) in
my attempts to clean it off.

If anyone actually KNOWS what this white stuff is, I'd be curious!

I do. However, if you want a microscope photo, I'll bring the "moldy"
screwdriver from home, put it under the microscope, and take some
photos. I assure you that it's plastic, not spores.

It's either a chemical coating or it's a mold-like growth.

Yep. It doesn't grow. Therefore, it's not mold.

My early Craftsman tools, when they were made by Miller Falls, do not
collect plastic rot.
http://oldtoolheaven.com/history/history.htm
The later Craftsman tools, probably made in China, have the plastic
rot problem.

It had coated that screwdriver handle with a white persistent but
powdery on the outside surface coating just like the picture the OP

http://802.11junk.com/jeffl/pics/drivel/plastic-rot.jpg

Grumble. That's my picture and I'm NOT the OP. The tools with the
acrylic coating are kinda rough, but plastic rot. The two with
plastic rot may have been added after I coated the others. I don't
recall.

I considered throwing the screwdrivers away, but, my sense of
tool preservation had me soak that screwdriver maybe 15 years ago
in all sorts of horrid solvents (acetone, bleach, acid, etc.) in
my attempts to clean it off.

The only things that actually directly attacked the white stuff were
mild plastic solvents. However, anything that dissolved the white
stuff, also attacked the plastic handle, so that's not a good fix.

If anyone actually KNOWS what this white stuff is, I'd be curious!

Send it to a pathology lab and see what they say.

Well, you're famous for having the right answer in the electrical
realm, so, I would have to give you the benefit of the doubt in
the mechanical.

It doesn't grow. Therefore, it's not mold.

True. It just sort of sits there. Minding its own business.

Grumble. That's my picture and I'm NOT the OP.

Ooops. Sorry about that. Your picture, as always, was perfectly apropos!
Too bad the OP didn't have the skills you have for Internet nntp work.

Come to think of it, VERY FEW people have your skills. You've helped
me quite a few times (under various nyms) on the wireless side, what
with that lousy set of WISPS in the SC mountains (yea, Brett, you know
him as I do. He's nice enough - but he's too busy and harried to give
you the technical time of day, and Dave, well, I'm glad I dropped
them).

The only things that actually directly attacked the white stuff were
mild plastic solvents. However, anything that dissolved the white
stuff, also attacked the plastic handle, so that's not a good fix.

I seem to remember I soaked mine in a variety of nasty solvents,
none of which worked - and then - about 10 years ago (or so, as I
don't really remember), I just scraped them clean. Have been that
way ever since.

Your explanation makes more semse than "mold". The OP did not say
what type of handles or tools were/were not affected, or if the tools

Wow. The real Jeff Liebermann (two n's and i-before-e) on alt.home.repair.

That's only because I crossposted to alt.home.repair and
sci.electronics.repair. If you want more of him, you have to go
to the second ng.

I've long wished there was an easy way to tell which ng someone is
posting from. I once put in my .sig, "probably posting from nnnnn",
"probably" because I also read the other group directly sometimes, but
it disappeared with a liater installation of Agent.

I'm impressed. You're the expert in the SC mountains for wireless radio.

Wow, I wouldn't have known that if I hadn't crossposted.

Glad to have you here.

I am VERY FAMILIAR with this persistent "white stuff".
I have no idea WHAT it is - but I have it too.

It's either a chemical coating or it's a mold-like growth.
It does seem to be hugely persistent, in that if you don't scrape it
away, it will last (seemingly unchanged) forever.

Interestingly, I don't have to scrape mine off. I can brush it off
with my finger, or a paper towel iirc. Of course that doesn't apply
when it's in a crevice or crack.

I remember segregating my white-coated tools a while ago, but I no
longer do that once I manually scraped them (mostly) clean.

I seem to remember that the white stuff "infected" other tools, but,
it's no longer doing that (after twenty years). But, that white stuff
you see in this photo is easily twenty years old!
http://www5.picturepush.com/photo/a/...g/12297573.jpg

It had coated that screwdriver handle with a white persistent but
powdery on the outside surface coating just like the picture the OP
posted over he
http://802.11junk.com/jeffl/pics/drivel/plastic-rot.jpg

I considered throwing the screwdrivers away, but, my sense of
tool preservation had me soak that screwdriver maybe 15 years ago
in all sorts of horrid solvents (acetone, bleach, acid, etc.) in
my attempts to clean it off.

If anyone actually KNOWS what this white stuff is, I'd be curious!

*Plastic* dust that grows? Sounds like a new life form! The OP did not say what exactly is he doing in the workshop but I am pretty sure if it was something that creates a lot of dust of any kind, he'd mentioned it.

Perhaps it's technically not mold per se (not fungal) but it's still biological - you've touched the handles, you've left some residue behind (sweat, skin flakes), bacteria are thankful for it, eat it and multiply. Still the same type of concern as with mold - something grows in your basement that you don't want. I would think some air movement and dryer air, just like with mold, would help and perhaps introduction of UV light in there wouldn't hurt either. Like those disinfecting lights in hospitals.

Also, I would think that just wiping the handles with alcohol would do pretty much the same thing as spray-painting Krylon on them - it will kill most of the bacteria that's on in now (though not all of course) and will simply delay its growth until some later point in the future when bacteria will inevitably catch up if they still have something to feed on.

It's not mold. It appears to be mold, but if you look carefully, it
doesn't "grow" in a radial pattern, as you would expect real mold to
grow. I've put the dust under a microscope to be sure. It's plastic
dust. Hit is with some heat, and watch it melt. I get this plastic
"mold" on most of my cheap plastic handle tools. The plastic breaks
down along the surface and sorta crumbles. It's probably caused by
exposure to something in the air, which condenses onto the surface
when wet. Washing the stuff off with any kind of kitchen cleaner
works, for a while.

The white rot is plastic, not mold. So it is written, so it must be.

I scraped some of the white stuff from the plastic handle and put it
under a x100 microscope.
http://802.11junk.com/jeffl/pics/white-plastic-rot/
Not the best photos but I'll try again after yet another Friday night
customer crisis. The photos show absolutely no structure, self
simularity, or colonies characteristic of mold.

I also heated some of the white stuff on a microscope slide. It
melted like plastic (burning my fingers in the process). The white
stuff also disolved nicely in acetone.

Drivel: Besides the Mercedes fuel pump, todays repairs were a
Bernzomatic trigger start propane torch (cold flow PTFE igniter wire),
an iPhone 4 with a non-functional standby push button (I gave up), yet
another HP LaserJet 4250 printer with sticky relays (replace felt
pad), and helped mount the landlords bicycle rack on his SUV.
Sometimes, I wonder what business I'm in.

And so I gather will the nut driver handle.

Yes, you certainly deal with a wide range of stuff. What business ARE
you in? :-)

For a while my home phone was broken and my cell phone was lost (in
the house) and I was using Skype to call out.

I didn't sign up for a Skype phone number yet, however. If someone
calls when I'm not there, can the caller leave a message, or at least
his phone number??

Is this a problem? In my drawer of rarely used nut drivers, blue is
also affected.

That's a tough question to answer. Basically, I separate my customers
from their money by providing a wide variety of services. It usually
involves some form of electronics, but also includes oddities such as
sewing machine repair.
http://802.11junk.com/jeffl/crud/Kenmore-sewing-machine.jpg
It is not unusual for me to repair appliances after fixing their
computers. As one business wanes (I was once in the calculator repair
biz), I expand into adjacent businesses. I find it helpful, but not
necessary, to know what I'm doing.

For a while my home phone was broken and my cell phone was lost (in
the house) and I was using Skype to call out.

Many cellular vendors allow you to activate a new phone, on an
existing number, via their web page, or via the phone. For example,
with Verizon, you dial *228. Buy a spare qualifying Verizon phone on
eBay for a few dollars and throw the spare where you can find it (i.e.
your vehicle). When you lose your phone, just activate the spare
until you find it. Also, make sure that the spare phone you purchase
is "clean".

calls when I'm not there, can the caller leave a message, or at least
his phone number??

No. Incoming calls from the PSTN cannot be received without a Skype
account that includes an incoming phone number. Without a phone
number, there's no way for anyone to dial your computer from a POTS
phone. What I've done is purchase a minimal account for a few
dollars, and use it only for emergencies. I've had about $15 on my
account for several years, with no monthly charges.

Similarly, Skype also charges for voicemail storage. However, if the
incoming caller uses Skype to originate the call, the PSTN is not
involved and your Skype client will show that you've received a call
from some person. The catch is that if you allow anyone to call your
Skype account, you open the flood gates to getting spammed and
solicited at your account. I have mine set to only allow calls from
people in my Skype address book.

About three years ago you retired, but like a character in an M. Knight
