I read the instructions on the "Great Stuff" can and it said that cleanup before setup can be done with acetone, but I used "Break Free Powder Blaster" to clean the application tube and nozzle and it worked fine. It probably contains acetone anyway.
People are like rifles. Some are tried and true, having great eyes, personality, and fun to be with. Others never seem to hit the mark with you. Still others go off half-cocked. Still, it's nice to know most of them.
