mold forms on cords, knobs, and tool handles

[micky]

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

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.

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.

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.

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.

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.

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... .

Try to store it in a plastic bag together with a package desiccant

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.

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.

Opinions seem to vary...

Wasn't the biblical plague of deaths of the first-born sons put down to the

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.

Maybe a photo will help:

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.

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.)

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

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.

*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.
