Super easy to use. Gets the job done.

Formula 420 cleaner seems to work as it should have only used it once so far.

. 4-20 is a great product. Cleans glass stains away with some simple shaking. You won't regret this product. All organic and even smells good. A great value. We use it to clean our lab glass and it just sparkles when done. A little rinse and done. Just try it....you won't be disappointed.

It actually keeps my glassware cleaner for longer. Also it smells like bubblegum but that smell goes away quickly. I ended up using the solution and salt with a brush and it seems to work better and my brush doesn't stink.

Best bong cleaner out there

I wanted to surprise my partner by cleaning his bong. As someone who does not partake, I did not know the first thing. 99% isopropyl and salt worked pretty well but for the life of me I could NOT get the hard to reach areas under those little "nubs" and it was making me CRAZY. This stuff is INCREDIBLE. Took mere minutes of light "shaking" and the bong, stem, and bowl look brand new! The smell reminds me a bit of blue icee but does make me a touch nauseous. *the bottle did seem to leak and lost a lot of liquid in shipping despite the seal sticker still appearing in tact. It did teach me a valuable lesson in crystals to liquid ratio & a little goes a LONG way. *For other newbs like me, the salt (if using iso)/crystals/grit does the heavy lifting, particularly in hard to reach areas. Regardless of the lesson learned, I don't think I would go back to the iso method because this was so quick, effective, and affordable. This formula also claims to be "non-toxic, biodegradable, and safe for glass, ceramic, and metal" (tho the ingredient list is not available and their website has an asterisk beside the words "non-toxic*"?) I will absolutely buy this again.

I have never had such an easy time cleaning my accessories.

Works very well for cleaning a really dirty bong. only downfall is the price of these bottles as it doesn’t come with a lot. I now use acetone/nail polish remover with salt as a substitute as it cleans very quickly and is dirt cheap and safe as long and you thoroughly clean with soap and water after use.

Wanted to clean this piece up and tried a couple homemade attempts. The gunk seemed like It was permanent (no picture, but the pipe was black AND plugged!). I bought a bottle of this stuff and followed the steps. I was shaking the glass for about 7-10 minutes, back flushed with hot water and BAM! Used probably half the bottle to clean everything, but I expect less for future cleanings do to regular maintenance lol. Before and after pics.

It didn’t clean my glass properly, no matter how much I shook it and let it soak :(
