I just ripped up my ~ 10 year old carpet in the living room and
hallway. In many areas there was a black gunk stuck to the hardwood
floor under the pad. It seemed to be confined to the high traffic
areas. It also was confined to the center portion of the hardwood
floor boards. Is this mold? The carpet has had a few dog accidents
over the years, but the areas were too large to be strictly from this,
plus the hallway seemed the worst and I don't recall ever having to do
any clean up there. I'm thinking I may have let it get too wet at some
point using the home carpet cleaner (bissel upright). Or is this just
a byproduct of the pad, dirt, dust, etc.?

I mopped up with spic & span plus bleach. I'll give it a second
cleaning tonight before the new carpet goes in tomorrow afternoon. The
new pad will have the waterproof membrane on top, so hopefully that
will minimize this in the future, if it is really mold I am seeing.

Had the same thing with a rental house I rehabbed last year. The pad
deteriorated in the dark spots and turned into this dark gunk that had
stained the carpet from below. The carpet pads from 10 years ago must have
been defective.

tev,

Not enough information. Can't see the black stuff fromhere. Where is
your house located. What is your climate. Is the floor over a
crawlspace, basement or slab? How cold do you run your AC? Etc.
Providemore information and we can give a better answer.

A lot of plastic products from "the old days" deteriorated over time, and
that might be all you're seeing. I had a nice aluminum camera case with foam
lining, circa 1973. About 5 years ago, the foam began turning into some sort
of god-awful goop the consistency of peanut butter. No liquids or other
substances ever came into contact with it.

While I can't ID it, it does sound like you have done what should be
done, cleaning and the bleach wash. I would not worry, unless there was
some indication of future moisture in those areas.

Of course if it were me, I would want to consider restoring the
hardwood, but to each there own.
