agree'dacetone and salt works miracles
Word! epsom salt and alcohol work great for pipes, but for larger pieces like bongs a few table spoons of rice with alcohol does miracles! Way better than epsom salt! Of course, you can't fit rice in a pipe unfortunately, so you'll have to stick w/epsom salt for the smaller glass.1 word rice
