Water Pipes become quite dirty and begin to smell after prolonged use. Over a long enough time the bubbler will develop a distinct unpleasant odor and the smoke drawn through it will acquire that taste as well. Depending on what material your water pipe is made from you may be able to quite easily clean without use of water pipe cleaning kits. While one shouldn’t put a plastic water pipe in a dishwasher. Many other techniques, such as simply scrubbing the interior with a brush will get good results. For strong residue stains in the chamber Epsom salts and rubbing alcohol mixed can be used as a soak and should remove buildup without much trouble. A laboratory glassware cleaning brush works wonders for scrubbing out resin and tar on the inside chamber of your water pipe. Be aware however, any soft glass water pipe can be scratched by these brushes.
