Randy's Black Label Cleaner is the perfect solution if you want to quickly clean your glass, metal, or ceramic pieces. Simply apply or pour it into your piece, shake, let it soak for a few minutes, then rinse with warm water. The process is lightning quick and will have your pipe looking good as new in no time! We especially like using this cleaner in larger pieces that would take way too long to clean using any other method, you can't beat the speed and results of using this cleaner. Randy's Black Label Cleaner is even the official cleaner of Illadelph, need we say more?
