Res Gel® cleaner is engineered to give your glass the best clean on the market. This natural, clay-based formula easily removes resin and tar from your glass bongs, rigs, bowls, stems, steamrollers, tools, grinders, jars, hands, and even clothes. It gets in every nook an crevice of your piece and stays there instead of draining out as a liquid cleaner would. Let it soak overnight for those impossibly dirty pipes. This patented formula is free of abrasive salts and is low in Volatile Organic Compounds, making it safer on your glass and friendlier on your environment. Res Gel® cleaning comes in an innovative "Shake-a-Bag" resealable pouch, making cleaning your bowls, stems, chillums, and small accessories a breeze.
