It does. The ones without a case smell just as bad (just got a bunch

Hmmm... I washed the tools and seperated the case from the tools for
a few days. I found that the odor came from the case, not the tools.
However, I did that maybe 15 years ago and only vaguely remember the

they stink, I'll try the test again.

Shotgunning is the true mark of a very poor tech. They don't
want to learn why things fail, or what parts are actually needed.

Might I respectfully semi-disagree?

I have always wanted to understand why something wasn't working correctly
before I fixed it. But as products have become more complex and harder to
troubleshoot, it seems increasingly necessary to, on some occasions, shotgun.
I don't like it, but if you're running a repair business, you have to get the
item out the door to stay in business.

If it's of any interest, I have never had a callback on anything I've
repaired. But that was in the days when virtually all electronics was composed
of discrete components you could unsolder and test, if need be.


William, the more you actually find the problem and repair what's
needed, the easier and faster it is to do on future jobs. You develop
an understanding for what kinds of parts are the highest failures, and
use logic to narrow down the problem. For instance, surface mount
ceramic resistors and capacitors have a low failure rate, but the
electrolytics have a high failure rate by comparison? Would you shotgun
a couple hundred chip caps, just in case? Would you replace a dozen
ICs, just in case?

The more parts you change on a modern surface mount board, the higher
the chances of destroying the board. It was simpler on tube radios, and
early discrete solid state designs, but it takes a lot of time and
expense to shotgun VLSI and ASIC ICs on a board.

Logical troubleshooting was the method I was taught in the mid '60s,
and after a few years on the bench I was the most productive tech.
Also, the repair costs were lower because I didn't replace as many
parts, nd the customer didn't have to wait for custom parts to be
ordered from the OEM, 'just in case'.

The microscope photos were awful, grainy, and somewhat otto focus but
sufficient to make a few observations:

I left the microscope setup in my office and will try to take some
better pictures with better objective lenses and better lighting on
Monday night. Bottom lighting didn't work because the "plastic rot"
was too thick. It also wrecked the focus as my depth of field is very
limited at x100 and x400. Maybe lower power will help.

I took some more photos, but they were about the same as the others.
http://802.11junk.com/jeffl/pics/white-plastic-rot/
The particle sizes are too thick to get a decent photo due to the lack
of depth of field. I just wanted one that shows the plastic like
shine, that is characteristic of plastics, and not mold. I'll melt or
set fire to the stuff later this week.

That joke goes back at least as far as William S Gilbert. He was tall and
authoritative-looking. A man mistook him for one of those people who stand of
hotels, and asked him to "Call me a cab".

"Very well... You're a four-wheeler."

"Wha...?"

"You said to call you a cab -- and I couldn't very well call you hansom."

The screwdrivers have never been in a case and still smell of xcelite.

they are in a case. No white powder, though.

My shop is in my basement, which has always seemed to be a very dry

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.

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.




I wonder if this is an example of an actual good use for WD-40? Too many
people use it as a lubricant instead of what it was designed to be - a
tool protective coating...

The question, since all my screwdrivers are from the 1980s,
is why some and not others would have the white stuff.
(Note: I inscribed the date on this screwdriver in 1981.)

I do think these white ones were those that I worked in hospitals
with at that time but I don't know if there is any connection.

Scrape off some with a knife. Put the scrapings on a tea spoon,
spatula, or metal something. Heat over a low flame. The melting
point of acrylic is 320F (160C). Monitor the temp with an IR
thermometer. If it melts and is kinda rubbery when warm, it's
plastic. If it burns, it might be mold.

Your screwdriver shows a finer pattern of plastic rot than my hex
wrench. It looks similar but may be a slightly different plastic type
(presumed to be acrylic). I can't tell from here.

If you feel ambitious, scrape off a sample, and mail it to me (address
below is my office) and I'll put it under the microscope and post a
photo. Be careful with the packaging so the USPS doesn't think it's
Anthrax or cocaine.

Any hint as to the manufacturer of the screwdriver?

I'm still not 100.0% sure about the white stuff. For example, what's
this?

The stuff leaking out of the alkaline battery is potassium hydroxide.
It can be cleaned off with any weak acid. Just smear on some vinegar
to the battery first. If it fizzes and foams, try doing the same to
the screwdriver. If you get the same fizz and foam, it's potassium
hydroxide.

The question, since all my screwdrivers are from the 1980s,
is why some and not others would have the white stuff.
(Note: I inscribed the date on this screwdriver in 1981.)

I do think these white ones were those that I worked in hospitals
with at that time but I don't know if there is any connection.

Well, if it is mold, it has to be one of the slowest growing mold
infestations I have ever seen. I used to manage my fathers apartment
building and I know (black) mold when I see it. The plastic stuff is
nothing like it.

Oops. The electrolyte is potassium hydroxide. The white residue is
potassium carbonate.
2KOH + CO2 - K2CO3 + H2O
Sorry(tm).

Any hint as to the manufacturer of the screwdriver?

Hi Jeff,

They're all Craftsman screwdrivers, all bought in the
1980s from Sears. The 3 I have with the white stuff were
used when I worked in a hospital fixing biomed equipment.

I'll get it to you; I can drive to your office also.
It would be worth the trip just to put this decades-old
mystery to rest.

We could also try the Myth-Busters up in San Francisco,
but this might not have the cachet of blowing things up
(but maybe we'll find a superbug?). :)

(I'll take this over to email for the visit as I'm not so
free with my personal information as you are.)

It's like a grey dust. (Or some other light color, I forget.)

As the OP, you have more responsibilities than the rest of us.

As such, would you kindly snap a photo of what you're talking about
so the rest of us can compare it to our screwdriver handles.
