First, run hot water through both ash catcher and your bong for a couple of minutes to get all loose debris rinsed out before cleaning.
I use Sea Salt and Rubbing Alcohol, add in a half a teaspoon of sea salt to the ash catcher and for the first rinse to get the big debris and oil out and with the second rinse, you add a half a teaspoon sea salt and fresh rubbing alcohol. The Bong only needs to be rinsed once with a tablespoon of sea salt and rubbing alcohol. Run hot water through bong and ash catcher for a minute or so apiece, then rinse with cold water for a minute fil with ice and Hit ON!!!!
One of the coolest parts of this is the alcohol does not dissolve the sea salt o you can use the mixture over again, I use a funnel and pour it back in the container and I can use it for about 20 bong washes!!!
STAY FREE, FLY HIGH, AND AS ALWAYS FUCK CANCER!
