acetone vs. mineral spirits

Ok, this question is for Goose (petro/chem guy) and Chucktx (paint guy)....mostly....or if you know the answer!!! I am getting ready to spray some base board trim with stain/polyurithane....clean up says to clean up with mineral spirits. I ended up picking up acetone.

1. Will acetone clean up this "polyshades" (brand of stain from home depot)?
2. have a paint gun...will it hurt the gun (chuck, same gun I have talked with you about before)....for clean up purposes....???

Thanks!

i dont use acetone verymuch so i dont know a lot about it....you can test a small piece to see what happens.....try to pic an inconspicuious place....as far as the cleanup....IF it will desolve the product you are using, it will clean the gun, but i would still run laquer thinner..."wash thinner" the cheap stuff through the gun to make sure that the accetone doesnt eat up the seals.....
mineral spirits is less volitle than acetone......it is used to remove fingernail polish.....mineral spirits is also very inexspensive at local wally's and k's...the wash thinner is also availabe at the same places......
here is what i would do....use the mineral spirits, clean gun after use with wash thinner.....hope this helps

Thanks. I was just not sure....think that I will error on the side of safe....better to do it right the first time then worry about it. I will go to the great wally world tomorrow and get the RIGHT stuff.....Laquor thinner and will also look around for that wash stuff you are talking about. so, my wife now has about 1qt of hard core fingernail polish remover!!!

the cheap laquer thinner is wash thinner................
