01
Isopropyl Alcohol & Coarse Salt
For borosilicate glass bongs and pipes, use 91%+ isopropyl alcohol combined with coarse sea salt as a gentle abrasive. Swirl gently for 2–3 minutes.
02
Warm Water Rinse
Rinse thoroughly with lukewarm water until completely odorless. Never shock hot glass with ice water to avoid thermal micro-cracking.
03
Routine Downstem & Bowl Care
Soak smaller glass accessories in a sealable bag with alcohol and rinse weekly to maintain optimal percolation and clean airflow.
