Depending on the degree of soiling and size of the bong, fill in 1-3 tablespoons 'Schmand Weg', possibly seal kick and the grind hole with a stopper and fill it with hot water. Wait 10 minutes, shake and pour it out. Rinse with hot water until the water is clear again. If necessary, repeat the process. Finished!
The bong with percolator, diffuser, HoneyComb etc. shines again in fresh splendor and looks like new, without any effort. Smaller parts such as bowls, screens, bangers, adapters etc. can be plunged in a solution of 'Schmand Weg' and hot water for about 10 minutes – clean again! 'Schmand Weg' is suitable for all bongs and pipes made of glass, ceramics and (not anodized) metal. Not suitable for pipes made of acrylic or other plastics.
