Formula 420 Cleaner - Glass, Metal and Ceramic - 12 Oz. Bottles. 2 Pack

When u see the price u think 🤔 mm should I? The answer is yes! This stuff takes off the sticky icky in minutes not hours. It says one minute but it's more like 25 minutes but still that's freaking great. It's non toxic the smell ain't too bad. Compared to acetone it's above & beyond. Comes in bottle form it's a crystal mix with liquid & blue in colour. Shake it good. I used a Ziploc bag poured it in threw my pieces in one at a time & shook like hell. Dang.. when u see how fast this stuff works it's worth it's weight in Gold my friends. U just pour it in ur bongs & shake. Boom like magic it's clean. If ur pieces or hands r sticky but clean just pour a lil in ur hands & rub it it away. Easy so flipping easy. The crystals dissolve in water so u can pour it down ur sink with no issues. Use soap to wash up. Don't taste this stuff not sure why u would, but Don't. All in all it's the best I've found & used. 10/10 Makes old glass new again & again. Luv it

Great product, very well priced. cleaned my bong so well it looks brand new. Very easy and quick just poured it in to the bong, shook vigoursly, and then rinsed out. Took about a minute. And the two bottle is going to last me a while.

Works like a charm:)

Works exactly as described but I usually have to do it twice to get everything.

This stuff is amazing getting the pipe clean. I would recommend something to close the ends as one shakes it. The smell is pleasant, seems like there is a lot of the material they used to scrub versus the liquid amount. It is a good size for the price and does not leave a taste to the pipe.

. 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.

Works pretty dang well! I was actually surprised at the amount of gunk the cleaner removed for the short amount of time it was exposed to the gunk. I used on a silicone piece, even. Color is light blue. Used only a handful of drops on the first go, and only have used it once, so product may last quite awhile.

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 had dome old glass that sat dirty for a couple years. boiling water, Iso, orange chronic, and even a magnetic scrubber wouldn't remove the resin from the glass, but just an 1/8 of this bottle made the glass crystal clear and looked like the day I bought it. Well worth it if you like to neglect your glass and even if you clean it regularly you just need a half OZ and a little water to get the job done

Works pretty good but still left behind some residue. Got most of the mess tho and I'm still happy with the results.

Everything was delivered fast and on time. The 420 is clearly a high quality product with a nice smell and good ingredients. I do though believe it requires some practice the totally perfect the cleaning process as so far there is still some resin remaining.

Worked okay but didn't get glass bong completely clean at all. Also smells super weird and not in the usual way cleaner does. Going to pass on this product.
