How to Clean Silicone Bongs and Dab Rigs

Not Sure How to Clean a Silicone Bong?

Silicone bongs and pipes are a special breed of weed pipe with many advantages over glass bongs. Silicone bongs and dab rigs are made for particular smoking jobs involving adventure, flexibility, and durability. A silicone bong has all of these qualities, so there is a good chance that adding one to your collection will improve your smoke sessions.

The best thing about silicone is that it can withstand impacts and high temperatures. You don’t have to worry about melting your pipe like a cheap acrylic bong, and dropping or tipping it is not a problem. If you are accident-prone or want to bring a bong to the great outdoors or a rowdy house party, then a silicone bong is the best.

You have to clean your silicone bong differently than a traditional glass bong. Solvents are not excellent for silicone and can eat away at the silicone surface. You cannot soak a silicone bong like glass in cleaners and solvents. There are ideal ways of cleaning a silicone bong and some more accessible aspects.

Are Silicone Bongs Easy to Clean?

Silicone bongs are relatively easy to clean compared to glass bongs if you follow a few steps to clean them properly. If you have the suitable materials and methods, your silicone bong or dab rig can be washed quickly with minimal effort.

Methods for Cleaning Silicone Bongs

There are many ways to clean a silicone bong, but some are better than others. Hand washing your bong is the most reliable way to remove all the resins, but you can also freeze, machine wash, use an approved silicone cleaner, or even soak it under the right conditions. Let's take a look at how to get each method done.

Boiling Water

You can remove nearly all the stuck-on grunge from a silicone bong with boiling water when done carefully. Boiling water is hazardous, and you’ll want to be careful not to splash or spill it when you are using it to clean. Make sure you have some rubber cleaning gloves or oven mitts ready to protect your hands. Remove any non-silicone parts from your bong, like plastic clips or glass bowls. Boil water in a kettle and place the bong on its side in the sink. Use a drain plug to keep the sink from draining.

Gently pour the water into the downstem hole of the joint. You should see loose bits of resin or other build-up being loosened and drained out of the bong. You may want to alternate pouring the water down the mouthpiece or bong and the joint. Repeat this process as many times as you need until you no longer see resins loosened.


It’s not advisable to soak silicone in solvents like alcohol or use harsher ones like acetone since they can wear away at the composition of silicone. If you want to do a soak treatment to your bong, the best way to soak it is to place it sideways, submerged in a container of hot water and dish soap. Leave the silicone bong submerged overnight and wash it thoroughly with hot water the next day. You should see many loosened build-ups wash away in the rinse from soaking overnight.

Hand Washing

You’ll want to use a scrubbing brush and soapy hot water. A long scrubbing brush snaked into the mouthpiece and downstem is beneficial. You’ll need to wear dish gloves. 

Simply clean the bong the way you would a glass cup, and make sure to get deep down into the bong's base if you can. The base where the water sits is where most of the build-up will accumulate over time. Cycle through, scrubbing the interior of the bong with rinsing it out. After a few cleaning cycles, let the bong dry and test inhaling from it without placing the bowl. The air should be free of resinous flavors, and there should be no pronounced soapy flavor either.

Freezing silicone


This method works exceptionally well for silicone dab rigs but can also be used for bongs. Silicone is resistant to heat and cold, which means that you can throw your bong in the freezer and try and freeze off some of the built-up resins and dabs.

The main trick to the freeze-clean method is to make sure the bong is free of any moisture. If any part of the bong is wet, then it will work to adhere particles to the bong. Ice can still be cleaned from the silicone, but it will be much easier to clean if it is dry when it goes in the freezer. Let it sit for several hours, and then use a long tool like poker or a clean dabber to chip off the frozen resins.

3. Put the silicone bong in a ziplock bag.

Put your pipe in a zip lock bag. You can bend silicone bongs and pipes and fit them inside a large zip lock bag or wrap the bag in freezer wrap. The reason for this is to keep moisture out during the freezing process.

Method #3: Using Vinegar on Silicone Bongs

Vinegar is a typical household cleaner that can clean silicone. Vinegar is best used for minor and routine cleaning because it is a mild acid.

1. Follow steps 1-2 from the boiling method.

Give your bong an initial wash and rinse with soapy water and let it dry.

2. Fill the silicone bong with vinegar.

Fill up the bong with vinegar and allow it to sit for fifteen minutes.

The vinegar will loosen the bonds that keep the resins stuck to the bong. Use warm water to wash away the vinegar and the stuck on resins.

Using Rubbing Alcohol on Silicone Bongs

As noted previously, solvents should be used sparingly on silicone bongs because it can degrade the material. Only use alcohol to wipe down the surface of your silicone bong.

Soaking is good for breaking down stuck-on resins and gunk. Scrubbing will use less of the cleaner since it involves putting a small amount of the solution in the bong and using a tool to scrub and clean the resins off. Using a silicone cleaner as a rinse involves pouring it through the bong multiple times and reclaiming the cleaner in a container to be reused. This rinsing process can work faster if the cleaner is combined with hot water.

How often can I boil my Silicone Bong?

The boiling method to clean bongs can be used frequently without harming your bong. If you use it occasionally to remove stuck on resins and build-up you will want to be sure that the bong maintains its shape. When the silicone is heated it is more pliable and can hold an altered shape slightly once cooled. Just make sure your bong is standing upright while cooling to avoid any unwanted changes.
