question, I own a home and just started renting a room out to a friend. I have been helping him sell some gadgets online (he makes them himself). he purchased hard plastic tubing to make the items (it's pretty small tubing). he buys the tubing in bulk. he uses pure acetone to remove some manufacturing numbers that are stamped on one side of the tubing. he uses a cotton swab and dips it in a pint bottle of pure acetone and then uses the swab to blot out the stamped number. I think that's great. however, he's doing it on my living room floor which concerns me. and what concerns me even more, it he spreads out some newspapers to work on and lets the area of the plastic tube dry (the area where he blotted out the stamped number). is this safe? sorta safe? or not safe at all? and when I say safe, I mean safe on the living room floor of someone's home. I really thought laying newspapers under it is a stupid idea. I know nothing about pure acetone other that I read it is fl
ammable. my roomate just told me it was fingernail polish remover (which women use all the time in the house) so it should be no big deal to use in the house. all responses are much appreciated. I asked him to take it outside, but he told me he would be extra careful. it's starting to get cold where I live (that may be one of the reasons he doesn't want to take it outside).

thanks

It isn't a good idea, in any setting, to keep the main container open
and dip into it....a spill could be a disaster. If the friend is using
more than a tsp or two at a time, I would insist that he take it
outdoors. Sounds like he needs some discipline and education

Better than newspaper on your floor, it might help to put something
solid (at least heavy duty foil) between layers in case there is a spill
so fumes don't get to the floor. Be sure he bundles up if you send him
outdoors

The size of the project would be useful to know....any chance 3M pad and
dish detergent will take off the markings? Might be just as effective
and safer.
