Formula 420 Natural Cleaner When your glass is coated with residue, the solution is usually to scrub and soak it for a while. The Formula 420 natural glass bong cleaner streamlines that process with a solution that offers clean glass in just seconds. Simply load the solution into your glass and shake. The glass will be as good as new without any of the hassles that come with most cleaning solutions.  Formula 420 natural bong cleaner is made with all-natural ingredients that are non-toxic and biodegradable. It both cleans and deodorizes your glass in just seconds, eliminating any smells or stains accrued from usage. The product can be used on glass, pyrex, metal, and ceramic materials, and will ensure pristine cleanliness that used to only come from scrubbing.  The bottles come in 16 OZ, and the AbrasiveAction™ will ensure that your smoking tool is clean after a quick tap water rinse and a few shakes. In case you don’t live nearby a smoke shop that has some natural bong cleaners, don’t hesitate to order from our online smoke shop.
