For something a little more environmentally friendly, Grunge Off is our favorite natural bong cleaner. This biodegradable solution uses no abrasives (like salt), no harsh-smelling chemicals, and is easy on your skin while not being any less effective. Grunge Off only takes minutes to work, requires no scrubbing, and is reusable! After using the solution you can strain out the gunk, or just pour it back into its original bottle for future use.
