Clean bong, better taste, less draw resistance – and it simply looks like new again. In this guide, you'll learn how to maintain your bong with just a few steps, reliably remove stubborn residue, and get rid of limescale deposits. We'll incorporate tried-and-tested products from the Schall & Rauch range – from Schmand Weg to Bio Reiniger and Anti-Kalk all the way to matching brushes.
Why clean regularly in the first place?
- Better taste: Old residue distorts flavours and causes harsh hits.
- Easier draw: Resin and particles clog diffusers and percolator slits.
- Longer lifespan: Clean glass or acrylic parts are less prone to breaking and scratching.
- Hygiene: Germs thrive in warm, stagnant water – regular cleaning prevents this.
