No Offense Intended to the Original post!Acetone does a Damn good job of cleaning dryed paint,caulking,silicone sealant,& even cured JB Weld from,just about any surface.It has an Extremely LOW Flash-point,making it Extremely Volatile.The pores of your skin will Readily absorb this Chemical,It is basically made from Ultra-Refined Wood Alcohol,& It is Toxic!It melts most plastics,& Stinks to High Heaven!I'm fairly certain it is the main Ingedient of Nail Polish remover,check the ladies stash,open it up & That smell will tell you,Right away!I would call it a Multi-use chemical for sure,but the only skin one would care to contact this with would be that of The Common Zombie!I use this stuff on a daily basis,at work, with gloves,Mask,& Lotsa' Ventilation!
