Re: Cleaning hookah
Like wildman said, use baking soda, and if you want some reactions for cleaning pour something lightly acid (vinegar, lemon juice). Or maybe club soda. Bubbles rock.
I use vinegar-water solution soak for tough cleaning, usually 4 hours if something horrible happened (or mizo watermelon). Then do hot water and than I find any remaining ghosted flavors (see: mizo watermelon) can be smoked out.
