Cleaning & Care

One of the biggest advantages of a straight downstem is how easy it is to clean. Because there are no slits or percolation holes, residue has fewer places to build up.

How to clean:

  1. Remove the downstem from your bong
  2. Soak it in a glass-safe cleaning solution
  3. Rinse with warm water
  4. Let it dry fully before reinstalling

For best performance, keep the bottom end submerged in water without overfilling to avoid splash-back.
