Although there are premade cleaners to use in your bong. 91% isopropyl alcohol and coarse salt such as Epsom Salt work great! DO NOT rinse your CUSTOM ADOPT A BONG SERIES bongs with Hot water! Certain glass such as our custom bongs we sell can not tolerate the heat.
1. Pour the alcohol of 70% concentration or higher in the glass chamber when it's still warm and hot.
2. Then pour some salt into the glass chamber via its mouthpiece, the coarser the salt, the better.
3. Cover the mouthpiece and slide hole with your palms, hold it tight and carefully, shake it up until the water changed to a dirty brown.
4. Pour the dirty water down the sink.
