1. Lemon Juice

If you add about 10 drops of lemon juice to the water, it will prevent residue from forming to the side of the glass.  The bong must be clean first though. This is not a perfect solution, but you will find that cleaning your bong will be easier.  This may help with residue that forms in the bubbler.

2. Isopropyl alcohol and Epsom salt

This is the most thorough method practiced by professional potheads after each session.   You will need one bottle of 99% Isopropyl Alcohol and a carton of Epsom salt.  Swirl a mix of alcohol, salt, and water around in the bong, sometimes several times, until the bong is purchase clean again. The salts work as a scrubbing agent and the alcohol as a solvent.

3. Everclear and Kosher salt

Same idea as above.  The everclear acts as the solvent and the salt will do the scrubbing.  If using this method to clean your bong, be sure to wash it out thoroughly, as the everclear won’t evaporate as well as ISO alcohol.

4. Isopropyl alcohol and Rice

This one sounds interesting.  Seems like a waste of rice though.

5. Grunge Off

6. Mouth Wash

Mouth wash is a surprisingly good bong cleaner, and as an added plus, it leaves your bong hits tasting minty fresh!

7. Ice Cream Salt and Isopropyl alcohol

Morton’s Ice Cream Salt (any brand will do but it’s just the one I prefer and can be found anywhere including K-Mart and Wal-Mart) and rubbing alcohol (the higher percentage the better).

Pour the ice cream salt into the bong (sorta like diffuser beads), and pour enough rubbing alcohol to moisten the ice cream salt and proceed to shake your bong repeatedly so that the ice cream salt rubs along the inside of the bong. Rinse with water and repeat until all the resin is removed. After a few of these your glass will be looking brand new.

8. Isopropyl alcohol

Just soak your dirty bong or pipe in alcohol for about 24 hours (if you can go that long without using it), and then rinse clean.  Most pieces should rinse clean after a single treatment.

9. Efferdent Denture Cleaner

Pop one of these tabs into your glass piece and you will have a nice clean bong.  Now you can clean your dentures, and you bong with one easy to use product.

10. Rubbing Alcohol and Cascade

The Cascade acts as an abrasive since it doesn’t seem to be very soluble in water. When you’re done shaking the piece, pour the alcohol out and put some warm water in the piece. The cascade will now turn into more of a soap and just rinse it out a few times with more warm water. It really gets rid of the alcohol smell and the glass will be super clean.


Overall, there are some major concerns that come with cleaning your bong.  Some methods may leave cleaning residue or soap inside your glass.  Be sure to rinse thoroughly after you remove your cleaning solution.  Also remember that we are dealing with glass here, so be sure to handle it delicately.  When swirling solution, be sure to grip your bong firmly at the base and hold the stem steady so you don’t create pressure cracks in the glass.
