I was responding to various parts of this thread, and this new keyboard has a stupid "power" button almost RIGHT above the damn backspace... I hit it accidentally, it closed the browser, and left me sitting here cussing.... so I went to the bathroom and pulled an empty toilet-paper roll from the trashcan, used a razor knife to cut a slit in it, and have it wrapped around the top edge of the keyboard, so I don't hit that damn power button (or the F12 to open the CSS editor!) anymore!!!! When I finally finish the roll of paper towels that's almost done, I plan to use that instead, to wrap around the entire row of F-keys! ARGHHHH!!!!
Anyway, yes, acetone will dissolve all sorts of things, starting with rayon (learned this with a Barbie dress when I was still in single digits!!), and running the gamut thru many plastics -- not a good idea at all with plastic tanks. It also takes your breath away, and I dunno, might even be one of those chemicals that folks could get high on, so really not a very good idea for a recovering person, and a really bad idea for cleaning anything made of polymer.
Vinegar is an excellent cleaner for MANY things -- glass, stainless steel, floors, all kinds of plastics... it doesn't smell very good, that's true, but gets the job done admirably, and won't cause an "industrial accident" (or gasping for breath!)!! (and I really don't know anyone who's ever been tempted to drink it!!)
