Nothing ruins a smoke session faster than the taste of stale water and burnt resin. A dirty bong isn’t just gross to look at; it ruins the flavor of your herb and harbors bacteria you definitely don’t want in your lungs.
If you aren’t sure how to clean a bong properly, don’t worry. It is actually easier than it looks. We have broken down the process into an eight-step method that removes stubborn gunk and leaves your piece sparkling.
Whether you are cleaning glass, silicone, acrylic, or a rig with complex percolators, we have the right tips for you.
Key Takeaways
- Best Method: Use 91% isopropyl alcohol and Epsom salt for the most effective clean on glass pieces.
- Frequency: Clean your bong 2, 3 times a week if you use it daily, or whenever the water turns cloudy.
- Material Safety: Never use alcohol on acrylic or latex bongs; stick to warm water and dish soap to prevent damage.
- Maintenance: Prevent mold and hard water stains by dumping dirty water immediately and rinsing with filtered water.
How Often Should You Clean a Bong?
The frequency depends on your usage habits. We recommend a full cleaning 2, 3 times a week if you use your pipe every day. If you are a casual smoker, clean it after every few uses.
Trust your eyes and nose. If you see a ring of resin, floating debris, or the water looks brown, it is time to clean it. If your bong smells like mildew or the percolator is clogged with dark spots, do not wait.
Bacteria and mold (biofilm) can grow in bong water within 24 hours. The bottom line: if it doesn’t look clear enough to drink (please don’t actually drink it), it is time to scrub it.
How to Clean a Glass Bong
Glass is the standard for a reason, but it shows dirt easily. The most effective way to clean a glass bong is with a mixture of high-percentage isopropyl alcohol and coarse salt.
The alcohol breaks down the sticky resin, while the salt acts as a scrubber to scrape away the gunk. We recommend isopropyl alcohol over acetone. Acetone is harsh, smells intense, and requires extensive rinsing to ensure it is safe to inhale from again.
- Time: 30 minutes
- Difficulty: Easy
What You’ll Need
- 91% isopropyl alcohol (99% is also great)
- Coarse Epsom salt
- 3-4 rubber bands
- Plastic wrap
- Sink or basin
- Ziploc bags (Gallon size)
- Microfiber cloths
- Dish soap
- Gloves (optional but recommended)
1. Disassemble and Rinse
Take apart your bong carefully. Remove the bowl piece and downstem. Place these small parts into separate Ziploc bags for later.
Dump out the old bong water into a toilet or sink. Rinse the main chamber with hot water. The heat helps loosen the resin before you apply the alcohol.
2. Add the Cleaning Solution
Pour your 91% isopropyl alcohol into the bong. You do not need to fill it to the top; fill it about halfway. Add a generous amount of coarse Epsom salt (about 3, 4 tablespoons).
The alcohol acts as a solvent to dissolve the resin, while the salt acts as an abrasive scrub.
3. Seal the Openings
Cover the mouthpiece and the downstem opening with plastic wrap. Secure the wrap tightly with rubber bands. You want a watertight seal so you can shake the piece without making a mess.
Pro Tip
If you clean your bong often, consider buying silicone cleaning plugs or caps. They are more secure than plastic wrap and make the process much faster.
4. Shake Vigorously
This is the workout portion of the cleaning process. Hold the bong securely by the base and neck. Shake it vigorously to get the salt and alcohol moving.
The salt will scrub the inside of the glass, removing the resin. You will see the liquid turn dark brown or black quickly. Shake for at least 2, 3 minutes. Let it sit for 10 minutes, then shake it again.
5. Soak the Accessories
Grab your Ziploc bags containing the bowl and downstem. Pour enough isopropyl alcohol into the bags to submerge the parts. Add a tablespoon of salt to each bag.
Seal the bags and shake them gently. Be careful not to let the glass pieces hit each other if they are in the same bag. Let them soak for 15, 30 minutes alongside the bong.
6. Rinse Everything Thoroughly
Pour the dirty alcohol solution down the drain (flush with plenty of water). Rinse the bong with warm water until the smell of alcohol is completely gone.
Do the same for your bowl and downstem. Use a pipe cleaner or cotton swab to wipe away any remaining residue in the tight corners of the bowl.
7. Clean the Exterior
The inside might be clean, but the outside probably has fingerprints and water spots. Dampen a microfiber cloth with warm water and a drop of dish soap. Wipe down the exterior glass.
8. Reassemble and Dry
Dry the outside with a clean cloth. Let the inside air dry for a bit before putting the downstem and bowl back in. Your bong is now ready for a fresh, clean hit.
Other Ways to Clean a Bong
If you don’t have isopropyl alcohol on hand, or if you prefer natural cleaners, there are alternatives. However, keep in mind that these methods may take more elbow grease for heavy buildup.
Using Boiling Water
We generally do not recommend boiling your bong. Glass is sensitive to thermal shock. If the glass heats up or cools down too fast, it will shatter.
If you must use this method, place the glass in a pot of cool water and bring it to a simmer slowly. Never drop a room-temperature bong into already boiling water.
Baking Soda and Vinegar
This is a classic eco-friendly cleaning combo. It is excellent for deodorizing and light cleaning but struggles with thick, caked-on resin.
- Add Baking Soda: Pour ½ cup of baking soda into the bong chamber.
- Add Vinegar: Slowly pour white vinegar into the chamber. It will fizz aggressively, which helps loosen dirt.
- Wait and Rinse: Let the mixture sit for 30 minutes. Rinse thoroughly with warm water.
Using Rice
Rice can work as an abrasive if you don’t have salt. However, be very careful if your bong has a percolator (perc). Rice grains can get stuck inside the small holes of a perc and are nearly impossible to remove.
To use this method, mix warm water, dish soap, and ¼ cup of raw rice. Shake vigorously as you would with the salt method.
How to Clean Different Types of Bongs
Not all bongs are made of glass. If you have a silicone or acrylic piece, the alcohol and salt method can actually ruin your gear. Here is how to handle different materials.
Latex or Acrylic Bongs
Acrylic and latex are sensitive to chemicals. Do not use isopropyl alcohol on these materials; it can cause the plastic to crack or dissolve over time.
Instead, use warm water and dish soap. Avoid boiling water, as high heat can warp the plastic. Use a bottle brush to scrub the inside of the chamber gently.
Silicone Bongs
Silicone is durable and heat-resistant. The easiest way to clean a silicone bong is to put it in the dishwasher. Take the piece apart and run it on a normal cycle.
However, silicone holds onto smells. If the dishwasher doesn’t cut it, you can freeze the bong. Place the silicone piece in the freezer for a few hours. The resin will freeze and become brittle, allowing you to crack it off by squeezing the silicone. Shake out the frozen chunks and rinse with soap and water.
Removing Hard Water Stains
If your bong is clean but looks cloudy or foggy, you likely have hard water stains. These are mineral deposits (calcium and lime) left behind by tap water. Alcohol won’t remove these.
- Acid Soak: Fill the bong with white vinegar or lemon juice.
- Wait: Let it soak for at least an hour. The acid will eat away the mineral deposits.
- Swish: Swirl the liquid around to ensure it covers all foggy areas.
- Rinse: Rinse with cool, filtered water. Dry the outside immediately.
Tips For Keeping a Bong Clean
Maintenance is the key to avoiding those hour-long scrubbing sessions. If you treat your glass well, it will taste better and last longer.
- Change water daily: This is the golden rule. Dirty water breeds bacteria and mold. Dump it out after your session.
- Use filtered water: If you have hard water, use filtered water to fill your piece. This prevents those annoying white mineral stains from forming.
- Rinse after use: Give your bong a quick rinse with hot water after you dump the dirty water. This prevents resin from hardening.
- Store properly: Keep your bong away from direct sunlight. Sunlight can promote algae growth in stagnant water and can degrade silicone colors over time.
- Add lemon juice: Adding a few drops of lemon juice to your bong water while you smoke can help prevent resin from sticking to the glass, keeping it cleaner for longer.
FAQs
What Should You Not Clean a Bong With?
Avoid bleach, ammonia, and windex. These chemicals are toxic and difficult to fully rinse out. Also, avoid using acetone on plastic, acrylic, or silicone bongs as it will melt or degrade the material.
Can I Use Table Salt to Clean My Bong?
Yes, you can use table salt. While coarse Epsom salt or rock salt works better because it is more abrasive, regular table salt will still help scrub away resin when mixed with alcohol.
Where Do You Dump Bong Water?
Flush old bong water down the toilet. Pouring it down the kitchen sink can lead to lingering smells in your drain and potential clogs from resin buildup.
How Do You Clean a Glass Pipe In a Microwave?
We generally advise against microwaving glass pipes as it can cause them to crack. However, if you must, submerge the pipe in a microwave-safe container filled with water and dish soap. Microwave until the water is hot (not boiling), let it sit, then scrub and rinse.
How Long Does It Take for a Glass Pipe to Dry?
It usually takes 15 to 30 minutes for a glass pipe to air dry completely. You can speed this up by placing it in a well-ventilated area or using a hair dryer on a cool setting.
Can Bongs Make You Sick?
Yes, a dirty bong can make you sick. Stagnant water develops biofilm, which harbors bacteria, mold, and fungi. Inhaling through this can lead to respiratory infections and lung issues.
Is 70% or 91% Alcohol Better for Cleaning Bongs?
91% or 99% isopropyl alcohol is much better than 70%. The higher alcohol concentration dissolves sticky resin much faster and more effectively than the diluted 70% version.
