How to Clean a Bong: Step-by-Step Guide
Clean a bong with 91% isopropyl alcohol, coarse salt, and hot water. Step-by-step instructions for the chamber, bowl, downstem, and percolators.
A bong cleaning kit holds four core items: isopropyl alcohol at 91 percent or higher, coarse salt, rubber plugs, and brushes. Add gloves and a rinse container and the kit covers glass, silicone, and metal parts. A full clean takes about 5 minutes.

What Goes in the Kit
- Isopropyl alcohol, 91 or 99 percent. Lower concentrations leave water and take longer to break down resin.
- Coarse salt. Kosher salt or rock salt. Fine table salt dissolves before it scrubs.
- Plugs. Rubber or silicone stoppers sized for the downstem hole and the mouthpiece.
- Brushes. One long handle brush for the neck, one small brush for the bowl and downstem.
- Pipe cleaners. For percolators and narrow holes.
- Nitrile gloves. Resin stains skin and takes days to wear off.
- A zip bag or plastic tub. Holds the bong while it soaks.
Steps
- Empty the water. Dump ash in a trash can, not a sink.
- Pull the bowl and downstem out.
- Pour 2 tablespoons of salt into the bong, then add alcohol until the liquid covers the resin line.
- Plug both openings. Shake for 60 to 90 seconds.
- Soak 10 to 30 minutes for heavy buildup.
- Scrub the neck, bowl, and downstem with brushes.
- Rinse with warm water. Hot water on cold glass causes cracks.
- Air dry on a towel.
Tools for Specific Parts
Percolators hold water in the chambers. A pipe cleaner or a bent brush reaches them. Silicone bongs take alcohol and salt, but some dyes fade after 20 or more washes. Quartz bangers need a torch and a dry cotton swab, not alcohol inside the bucket.

What to Skip
Acetone, bleach, and paint thinner leave residue in glass and damage silicone. Boiling water cracks glass from temperature shock. Rice works as an abrasive but jams percolator slots. Dish soap clears surface film but does not cut resin.

Schedule and Storage
Clean a bong used daily every 3 to 7 days. Alcohol evaporates, so cap the bottle after each use. Keep the kit out of sunlight and away from heat. Replace brushes when the bristles flatten against the handle.
