I have an acrylic bong that looks like this one Acrylic Double Bubble Bong 'Hashish' - Acrylic Bongs - Bongs & Waterpipes - Smoking Pipes - Grasscity.com and I need to know how to clean it. It has a shit ton of resin stains on the inside, especially in the bottom bubble. I don't know how to wipe all of the stuff out. I know to use iso and salt but what is the best thing to wipe it clean after I soak it? Because its hard as hell to get down in there.
