I have those tiny dustlike black fungi that grow in the bathroom.
They're like very very fine black pepper but can become a significant
volume if left alone, and they're sometimes hard to rub or scrub off
the surface. Though I wipe them off, and sometimes it's hard, they grow
again. They also seem to be spreading to other rooms upstairs. I'd like
to kill them off.

I found this spray in a nearby store that's made especially for this
purpose. It's some antifungal spray. The only problem is that it seems
a little expensive at the recommended dose, ~4£ for each 2 square
meters. I have the bathroom and the whole upstairs floor to spray.

Does anyone know of a cheaper solution? Can bleach work? What about
vinegar?

Many thanks and regards.

Where do you live? What season is it right now?

A northern part of Europe where the temperatures these days average ~ 0
c. I shower at least once, usually twice and sometimes more a day, in
warm to hot water. I economise on heating otherwise and prefer to wear
layers instead. As a result it can get cold and a little humid indoors,
it's too cold to ventilate often. Wet things like towels could take
long time to dry, perhaps many days, if not heated somehow.

Perhaps I could open the window after each shower, perhaps I should.

It's not unusual for a bathroom to have mildew problems, but if the rest of
the house has problems, it's cause for concern. You really should find a way
to ventilate. Is it possible to install a bathroom fan?

Cut the showers down to one a day or fewer. It isn't like you are
sweating and stinking, and unless you are using moisturizers, you may
be drying your skin in addition to creating mold problems.

If the place is cold enough that you have to take numerous showers to
keep warm, you have other problems.

I don't take showers to keep warm per se (well, that's a side effect,
perhaps a nice one sometimes), I'm just obsessive compulsive about
cleanliness. I do get skin dryness problems, which I remedy by rubbing
sunflower oil after a shower as an alternative to chemical
moisturisers. For my hands though, which I wash often, I do use the
chemical ones. I'll try to shower less, once or twice a day, but never
more. I'll also open the window after each shower.

I need to do something about this black mold. After reading around I
think I may perhaps try a mixture solution of white vinegar and
detergent first, if that doesn't work, maybe I'll try baking soda, if
that doesn't work, maybe I'll try bleach after a few days, as per page.


http://www.thebestcontrol.com/bugstop/control_molds.htm

I'll also wear gloves, dust mask and eye protection when dealing with
them. I need to buy dust masks and eye protection anyway because I'm
using power tools these days.

bleach water mix should work. oxy bleach works well, too.

Try baking soda?, Try Vinegar, Try detergent? just do what works and
kills mold by removing the plants Oxygen , Bleach. Try a Dehumidifier,
you obviously have an excessive humidity environment that mold thrives
in and can cause illness. Or try 2 showers a month instead.

Or 10% bleach. Real chlorine bleach, not the "gentle" oxygen bleach.
Should both kill the mildew/mold and bleach out the black spots.

Yes, do something, you may not be sensitive to its toxins yet but it can be
cumulative. I have a friend who was made seriously ill (pneumonia)

What you are cleaning is the fruting bodies of a larger fungal colony. The
fungal filiments reach deep into the wallboard and you cannot kill all of it
without saturating the wall 100% which is not practical and will cause other
problems like crumbling.

Sorry to say the only solution is to completely remove all infected
wallboard and wooden studs in the area and replace. If moisture is s
recurring problem, use a wood preservative on the replaced studs and buy a
wallboard resistant to fungas. Use cement backerboard as a last resort.

Might as well take care of it right as any future buyer will need this
disclosed and if you do not and they get sick, you're open to a law suit.
If you rent,
insist that it is repaired immedietly as it is a health risk and grounds for
terminating a lease.

If you want a cheap spray. Use a garden product with copper sulphate in it.
It may stain but you can prime and paint if you can kill it first. There
are also paints with fungacide built in.

Fungus feeds on the paper in the wallboard. and thrives when warm and wet
but will still grow in less ideal conditions.

Vinegar is supposed to work pretty well, too. Just don't mix bleach with
vinegar, or you could generate some unpleasant after-effects . . .

It's cheap, too, so you could get a gallon jug, spray some on after each
shower, and see what happens.

I researched this stuff over the past couple of days. Mixing vinegar
and bleach is dangerous, it produces chlorine fumes, which are toxic.

"Acids with bleach. Generates highly toxic chlorine gas."

http://chemistry.about.com/cs/toxicc.../aa603003a.htm

The last one is worrying

"Hydrogen peroxide/acetic acid mixtures. May explode upon heating."

Vinegar is essentially acetic acid.

So, guys, I need your advice on this. I so far have chlorine bleach,
and I found some washing soda in the store yesterday and got it. I
didn't find white distilled/spirit vinegar (the one I found had ammonia
caramel colourant in it) so I'm going to another supermarket to look
for it tonight. I'll also look for some oxygen bleach.

Now, I want to kill this stuff as sure as I can. I therefore want to
apply as many substances as reasonable, as many times as reasonable.
What should I start with? then what?

I know that vinegar neutralises bleach, and that bleach and vinegar
produce chlorine fumes.

I have two things to deal with; 1. bathroom tiles and surfaces. 2.
wallpaper on cement.

Bathroom tiles and surfaces should be easy to deal with; saturate with
the substance and then rinse or wipe. It's the wallpaper that I'm not
sure what to do with. I know that I want to remove it all, and I
already have a steamer that'll do the job eventually, and then I'll
paint the room(s).

I'm thinking of perhaps saturating the wallpaper with washing soda
first. Then saturating them with vinegar (wait, perhaps I can just use
the one with the food colourant in it, since I'm removing it anyway).
Can I, if need be, after a few days, apply some bleach? Would it be a
danger? do you think I wouldn't need to anyway? perhaps I can use
oxygen bleach instead? perhaps I can forget about the washing soda and
vinegar and just apply bleach from the start?

What do you guys think?

Just use one product, dont mix, dont worry it will kill the mold, use
the laundry bleach and that is all. Even full strength it is apx 98%
water. It kills mold by removing the oxygen. After it is dead or the
next day you can clean the area with soap and water

you'll probably have to remove the wallpaper and replace it or paint.
if you paint, use something like kilz to prime the surface.

I think you've been watching too much "Monk."

1. If the wallpaper is on gypsum board, you don't want to soak.

2. Even if you remove every single mold spore, there will be more that
get blown into the room.

Yeah, my experience is go with the bleach. I wouldn't be surprised if
the mold just laughed at the vinegar.

Hi all. Thanks a lot for your help and advice.

I think I have everything I need right now. I have chlorine bleach,
oxygen bleach, distilled vinegar, and washing soda. I think i'll mostly
use the washing soda and the oxygen bleach first and spray it on them.
I'll wipe the surfaces, and I plan to try to kill the black mold on the
wallpaper first before I use the steamer to remove the wallpaper and
then paint the walls.

I'll also get a humidity sensor, keep an eye on it, and make sure I
ventilate often to keep the humidity down.

I'm somewhat worried about using the steamer, perhaps it'll spread the
spores everywhere. How does it work? are the spores the same as the
live organisms or are they different? Do the chemicals kill both the
spores and the live organisms? Should I use a chemical wallpaper
stripper instead of the steamer?

Perhaps I could open the window after each shower, perhaps I should.

yup. shouldnt be a problem if you keep the bathroom door shut as long as
the window's open.

best thing would be a bathroom ventilation fan in the ceiling, if thats
possible. ive got one, and it works ok. im thinking about upgrading to a
higher CFM one

I have those tiny dustlike black fungi that grow in the bathroom.
They're like very very fine black pepper but can become a significant
volume if left alone, and they're sometimes hard to rub or scrub off
the surface. Though I wipe them off, and sometimes it's hard, they grow
again. They also seem to be spreading to other rooms upstairs. I'd like
to kill them off.

I found this spray in a nearby store that's made especially for this
purpose. It's some antifungal spray. The only problem is that it seems
a little expensive at the recommended dose, ~4£ for each 2 square
meters. I have the bathroom and the whole upstairs floor to spray.

Does anyone know of a cheaper solution? Can bleach work? What about
vinegar?

A 1:10 bleach solution can kill them (1 part bleach, 10 parts water) but
there very well might be another source of the spores, like behind your
drywall. You must drill some holes in the drywall and look in there with
a flashlight (you might have to drill 4-5 inch holes to get a flashlight
and your eyeball in there.) If you have a behind-the-wall infestation
(i.e. that's where you can't clean and they can grow unmolested) you
have to take your drywall off, clean all surfaces with a bleach
solution, and put on NEW drywall.

Also check under your carpets, the pad could be holding moisture too. Do
a sniff test. Get on your hands and knees and try to find where the mold
smell is strongest, then pull up that area of carpet.

This is the procuedure most people use after a flood: Remove all drywall
(which holds water really well), remove any particle wood (like MDF
often used for sheeting/sheathing), and wash studs and weight-bearing
wood with bleach solution.

The last thing you have to do is find out why moisture is being trapped
behind your walls and feeding the fungi. Is there a moisture barrier
between the outside siding and sheeting? Not sure where code requires
the moisture barrier so consult a local builder.
