What, chemically, is that whiteish crumbly powder on bad batteries?

We all have seen it, and most of the time you can just brush it off, but
I have it on a device deep inside that I can't get a brush on without
breaking stuff.

I'd like to use a solvent (I already tried water but I want to do a
better job) that dissolves the stuff so knowing the chemistry might help.

Do you have any idea what the chemical composition of that stuff is?


Yesterday I stopped to offer a jump start for a fellow.
Turns out that his positive battery calmp (automobile)
had corroded off, due to battery acid. In this case,
I'd say the problem was lead suplphate, and some copper
sulphate. Real shame. Sunday about 5 PJM, in a parking
lot at a shopping center. Myself and the security guy
both tried jumping, and no luck. Fortunately, he had a
cell phone. Hope he was able to get his adult son (talking
to him on phone) to bring out a new cable. I suspect a
new cable would have done the job.
