Cleaning a bong is important to maintain its functionality and to ensure that the smoke is clean and tastes fresh. Here is a step-by-step guide on how to clean a bong:

1. Empty the bong: Remove all the water and any remaining debris from the bong.
2. Clean the bowl and downstem: Use a pipe cleaner or small brush to clean the bowl and downstem. You can also use rubbing alcohol and salt to scrub off any build-up.
3. Clean the bong itself: Fill the bong with warm water and add a small amount of rubbing alcohol. Shake the bong vigorously to remove any buildup. You can also use a bong cleaning solution specifically made for this purpose.
4. Rinse the bong: Empty the bong and rinse it thoroughly with warm water to remove any remaining cleaning solution.
5. Dry the bong: Shake the bong to remove as much water as possible, and then dry it with a clean towel or let it air dry.

Note: For bongs with intricate designs or hard-to-reach places, you can use a pipe cleaner or small brush to clean those areas.

It’s important to clean your bong regularly to prevent buildup of resin and bacteria and to ensure that you have a good smoking experience.
