Hey guys:
In all the dry weather we've had here in the NE (Yeah, right) some
shelving in the basement acquired a LOVELY layer of mold.
The shelving is steel Gorila Racks with particle board decking. Nothing
else down there is the least bit moldy--only the particle board, which
surprised me, considering all the icky chemicals involved.
My thoughts are:
1. Take the shelves out on a bright sunny day (yeah, right), to kill the
mold, then oil-base primer followed by "Kitchen and Bath" paint, hoping
to score some from the Borg Oops pile.
2. Replace the 1/2" P-board with 1/2" BC Yellow Pine plywood. I've
quite a lot of plywood scraps down there and none of them are moldy.
3. Something else?
What do you guys think?

I'll tell you what I did..Throw the wood away ASAP. There is no way to
clean them up. I have the same shelves and the wood looked like some
kind of high school science project gone bad. I have not seen that
many colors since I found the two month old meat loaf in the back of
the fridge. Is it something in the glue that they use? I just went
down to the local electronics store and picked up a 50 pint (that
seems to be the way they rate them) dehumidifer for $200 (the jointer
will have to wait a little longer)Does any one know what % of humidity
would be good to strive for?
Good luck

Some years back, SIL worked in store fixtures(show cases, checkout stands,
etc.) industry. One of their main materials was what they called "bearer
board", actually MDF. Machines smoothly, takes laminates nicely,etc.
NOW - - - he got some scraps and made basement shelves from them, and
surprise, they started looking green! Some research found one of the main
components of MDF is *FERTILIZER*, and we figured his shelves weren't
molding, they were starting to GROW stuff. To my thinking, particle board is
a relative to MDF, so FWIW, maybe this is your problem. I do however, agree
with Ramsey, the best thing to do is get rid of them and start fresh with
plywood, sealed and painted.

Around 50% is considered "normal" on my little humidity meter thingie.
Hygrometer? You might want to buy one for the affected room, so you can
get some sense of how well the thing is working. I got this one at
Wal-Mart, in Housewares. I don't remember how much, but it was cheap.
I bought one of those (dehumidifiers) for my crawlspace recently. It was
dank like a cave down there, with damp mud all over the top of the vapor
barrier from the flooding, including some big piles from various
excavations I had done in the course of trying to deal with the constant
flooding. I had visions of rot setting up, and having a nightmare on my
hands, but it took me a long time to scrape up enough cash. It was a real
relief to finally get this thing and start it running.
I set it for the max, and it ran for about two weeks (the water drains into
the sump I just dug, and gets pumped out periodically) before shutting off
for the first time. Now it runs off and on, and everything down there is
very nearly bone dry. There's a hard crust forming on those mud piles. I
don't remember what % "bone dry" is, but it's probably around 20%.
Anyway, I'm just saying they really work. Worth the money.

Depends on where you are. In some places teak is cheaper than pine or
plywood.
Around here I'd guess that #3 pine 1x shelving would be about 50% more
expensive than 1/2" SYP BC plywood.

All you need to do is wipe it down. You don't need to soak it
overnight or anything like that.

No water (or liquid to my knowledge) is compatible with particle
board. I'm still wondering what it is good for since it is a waste
by-product of the lumber industry. It disolves, breaks out and is
heavy and probably has noxious fumes. And I own a tree farm so I don't
hate the forest industry.

Check those brakes out on the way to Sam's to get you a de-humidifier!

But let's get down to the root of the problem. What caused it? If the
cause is not removed, he may have the same trouble again.

Throw the boards away NOW. They are not worth trying to save. Mold is
a horrible problem that you don't even want to think about so get rid
of it while you can. Clorox the rest and rinse well. Find out why mold
started. Do you need to go to Sam's and get one of their $80
dehumidifiers? Sounds like it. I use one in my house the entire summer
and throw away at least 3 gals. water a day.

Knotty pine is WELL outside of the budget for this sort of a project,
don't you think? Money'd be better spent on all steel Unistrut shelving.
I mean, you gonna dream, why not solid teak? :-)
Is bleech solution compatible with p-board?

Lotsa causes. This is the first time we've had problems with enough
damp to cause mold. Curious bit is that only the P-board seems to be
affcted.
So dehumidifier moves up the list right after the car's brakes, which is
rather more important right now.
