How to Clean Your Gravity Bong: 5 Essential Steps

Pour isopropyl alcohol into the bottom globe — about 10–15% fill is plenty for a regular clean. Screw both globes back on and flip the whole unit upside down a few times to run the ISO through all the percolators. Repeat this 3–4 times. The more you’ve been using it (especially for dabs), the more alcohol you’ll need and the longer this step takes. Dab residue builds up significantly faster than flower ash, so dab users should clean more frequently.

Step 3: Scrub Every Hole With Wire Brushes

This is where the wire brushes earn their place. Dip the brushes in isopropyl and work them into every hole you can reach — especially the percolator tubes. Use the small brush for the inner diameter holes and the larger brush to touch the outer edges. Go straight up and down when inserting the brush (angling it won’t let it go all the way through). Don’t rush this step — any missed residue will affect flavor and airflow next session.

Step 4: Clean the Hose Separately

Disassemble the hose completely: remove the glass piece, both magnetic connectors, and any other detachable parts. For the hose itself, pour some isopropyl alcohol in one end, plug both ends with your fingers, and shake it back and forth so the ISO coats the interior. Pour it out over the sink, then run water through the hose to rinse. Optionally use compressed air to blow out any remaining moisture. Leave the hose near a window with sunlight or airflow to dry completely — this is the one part that must be fully dry before reassembly.

Step 5: Wash Globes With Soap and Water, Then Dry Everything

Once the percolators and internal parts have had the isopropyl treatment, wash the glass globes with soap and water. Rinse all removable parts that had isopropyl contact under the tap — anything that could end up in the vapor path should be rinsed clean. The most important step: let everything dry completely. This means 4–5 hours minimum, or ideally overnight. Using your gravity bong before it’s fully dry means inhaling residual isopropyl, which you don’t want.

How Often Should You Clean Your Gravity Bong?

Now that you know how to clean your gravity bong, how often should you do it? If you’re using it as a daily driver, aim to clean your gravity bong at least once a week. Some cleaning guides say every couple of days, but that’s a lot of work for a device with this many components. The key is consistency — letting residue build up for weeks makes the deep clean much harder. For dab users, the residue accumulates faster so a weekly clean is more important. Flower users have a bit more margin.

Tips for a Deeper Clean

If you really want to know how to clean your gravity bong thoroughly — not just a maintenance clean — go further with the disassembly. The center piece can be fully unscrewed and removed — each sub-piece comes out individually, giving you direct access to every percolator channel. Use the Allen key to remove sections you’d normally leave in place. Soak stubborn pieces in isopropyl for 15–20 minutes before scrubbing. After a deep clean, the device will feel brand new and airflow will noticeably improve.
