Water pipes and glass accessories need proper care to perform well and last. This FAQ covers the most common questions about using, cleaning, and maintaining your pieces.
Using Your Bong
How much water should I put in my bong?
Fill until the downstem is submerged by about 1 inch. Too much water creates drag; too little doesn't filter properly. Experiment to find your preference.
What's the difference between MTL and DTL with bongs?
Bongs are typically direct-to-lung (DTL)—you inhale directly into your lungs rather than holding smoke in your mouth first like with a cigarette.
What temperature should my water be?
Room temperature works fine. Some prefer cold water or ice for cooler hits. Warm water can actually smooth hits too by adding humidity.
How do ice catchers work?
Ice pinches hold ice cubes in the neck. As smoke passes over ice, it cools significantly for smoother, less harsh hits.
What's a percolator?
A percolator is a chamber that creates additional bubbles, filtering and cooling smoke further. Types include tree, honeycomb, showerhead, and matrix percs.
Does more percolation mean better hits?
More percolation means smoother hits but can reduce flavor intensity and create drag. Balance filtration with airflow based on your preference.
Cleaning
How often should I clean my bong?
- Water: Change after every session ideally
- Quick clean: Weekly for regular users
- Deep clean: Monthly or when visibly dirty
What's the best way to clean a bong?
- Rinse with warm water
- Add isopropyl alcohol (91% or higher) and coarse salt
- Cover openings and shake vigorously
- Let sit for stubborn buildup
- Rinse thoroughly with warm water
- Air dry completely
Can I use rubbing alcohol to clean my bong?
Yes—isopropyl alcohol (91-99%) is ideal. Lower concentrations work but require more effort. Rinse very thoroughly after cleaning.
What about using dish soap?
Dish soap can leave residue that affects taste. Isopropyl alcohol is more effective and evaporates cleanly.
How do I clean percolators?
Fill with iso + salt mixture, cover openings, and shake. Let soak longer for complex percs. Some people use hot water to loosen buildup first.
Can I put my bong in the dishwasher?
Not recommended. High heat can stress glass, and dishwashers won't clean inside complex pieces effectively.
Maintenance
How do I prevent my bong from getting dirty?
- Use fresh water each session
- Don't let dirty water sit
- Add a drop of lemon juice to water (reduces buildup)
- Use an ash catcher
- Clean regularly before buildup hardens
My bong smells bad—how do I fix it?
Deep clean with iso and salt. For persistent odor, let iso sit for several hours or overnight. Some use denture tablets or bong-specific cleaners.
How do I remove hard water stains?
Soak in white vinegar for several hours, then clean with iso. The acid in vinegar dissolves mineral deposits.
Should I use filtered water?
It can help reduce mineral buildup over time, but regular tap water is fine for most users.
Accessories
What's an ash catcher?
An attachment that sits between your bowl and downstem, catching ash and debris before it enters your bong. Keeps your piece cleaner longer.
What size bowl do I need?
Match your bong's joint size (14mm or 18mm typically). Check your current bowl or downstem to confirm size.
What's the difference between male and female joints?
Male joints insert into accessories; female joints accept inserts. Most bongs have female joints that accept male bowls.
Troubleshooting
Why is my bong hard to pull?
- Too much water
- Clogged downstem or percs
- Small opening (by design)
Why does my bong gurgle/splash?
Too much water. Drain some and try again. Splash guards also help if your piece doesn't have one.
How do I fix a stuck bowl or downstem?
Run warm water over the connection to expand glass slightly. Never force it—glass breaks. Use silicone grips for leverage if needed.
