Here’s How to Clean a Bong

Glass bongs are beautiful additions to cannabis smoking routines. They’re environmentally-friendly, they work to cool down the smoke before it hits your lungs, and they make conserving cannabis a breeze.

But everyone who’s ever had a bong knows that after a few sessions, it can get really nasty. Resin builds up, sticks to the glass, and changes not only the look of your piece, but the flavour profile of the smoke.

To maximize your experience with cannabis, you should change your bong water after each session and fully clean your bong once or twice a week, depending on your use frequency. I know, I know. It seems like a pain and that’s why so many of us procrastinate until the point where it seems almost impossible to restore our bong’s beauty. But it’s never too late.

Remember, a clean bong provides a healthier smoke. If you wouldn’t drink the water in your bong, you shouldn’t smoke with it either.

Here’s how to safely clean your bong:


  • Cleaning gloves
  • White vinegar
  • Baking soda
  • Fresh lemon

Step 1: Carefully disassemble your bong.

Wearing your gloves, begin to remove the individual pieces of your bong. Set your mouthpiece and pipe on a soft surface like a dishtowel beside the sink.

Step 2: Do a quick clean.

Right now, you’re really just prepping your pieces for deep cleaning. Empty the bong water and rinse the whole unit with warm water. Remove any plant materials from your mouthpiece and rinse with warm water as well.

Go slow to ensure you don’t accidently drop any of the glass pieces.

Step 3: Add your eco-friendly cleaning products.

Fill the base of your bong with vinegar and add a few teaspoons of pure baking soda. Cover the bong holes and shake hard for several minutes. When the vinegar has turned brownish, rinse out the mixture with warm water.

For separate items like the bowl and pipe, it’s easiest and most effective to gently place the pieces in a zip-top bag filled with vinegar and a dash of baking soda. Since these will likely be the dirtiest items, let them soak for an hour or so before rinsing with warm water and gently wiping clean.

If you regularly clean your bong, that’s it. One round of vinegar and baking soda is likely enough to restore your bong’s original beauty. Now...if it’s been a while, you may need to repeat this step or add in the next step.

Step 4: Use fresh lemon to cut through hard-to-remove stains.

For bongs that need a deeper clean, lemon is the go-to. It removes stains, smells amazing, and is a safe addition to any cleaning routine. Simply squeeze one whole lemon into the base of your bong and add some warm water. If you need an even deeper clean, make a lemon concentrate by soaking peels in vinegar for several days. Swish the lemon mix around until the whole bong has been covered. Rinse the stains away.
