1. **Gather your supplies**: You'll need isopropyl alcohol (at least 90% concentration), coarse salt (such as Epsom salt or rock salt), cotton swabs or pipe cleaners, and hot water.
2. **Empty the bong**: Pour out any remaining water or residue from the bong.
3. **Disassemble the bong**: If your bong has removable parts such as a bowl, downstem, or ash catcher, carefully remove them.
4. **Rinse with hot water**: Rinse the inside and outside of the bong with hot water to loosen any debris.
5. **Add cleaning solution**: Pour a generous amount of isopropyl alcohol into the base of the bong. Add a handful of coarse salt.
6. **Seal the openings**: Use your hand or a piece of plastic wrap to cover the openings of the bong (such as the mouthpiece and downstem). Shake the bong vigorously to dislodge resin and debris.
7. **Soak the parts**: If your bong has removable parts, such as the bowl and downstem, place them in a container filled with isopropyl alcohol and salt. Let them soak for at least 30 minutes to loosen any buildup.
8. **Scrub and swab**: Use cotton swabs or pipe cleaners soaked in isopropyl alcohol to clean hard-to-reach areas, such as the downstem and bowl. Use a brush or sponge to clean the exterior of the bong.
9. **Rinse thoroughly**: Rinse all parts of the bong with hot water to remove any remaining cleaning solution and residue.
10. **Dry thoroughly**: Use a clean towel or paper towels to dry all parts of the bong completely. Allow the bong to air dry for a few hours to ensure it's completely dry before using it again.
11. **Reassemble the bong**: Once all parts are dry, reassemble the bong and add fresh water.
12. **Optional**: If your bong has stubborn stains or residue, you may need to repeat the cleaning process or use a specialized bong cleaning solution.
Regular cleaning of your bong will help keep it in good condition and ensure you have a pleasant smoking experience.
