To keep your bong clean and functioning properly, you should rinse it with warm water after each use. Additionally, it is important to give it a deeper clean by taking apart your bong and soaking the pieces in a mixture of warm water and alcohol or baking soda. Allow the pieces to air dry before putting them back together for use. If you don't clean your bong for a long period of time this could lead to mold buildup, which can be harmful if inhaled over an extended period of time which is why it's best not to cut corners when cleaning! If there are too many hard-to-reach places on your bong, investing in a pipe cleaner or special cleaning solution product will help ensure that your new favorite piece won't let you down.
