Formula 420 Glass Metal Ceramic Pipe Cleaner 12 Oz. 3 Pack

I love using this for my bongs and parts for it. Its to easiest thing to use and literally cleans within minutes. It works perfectly and it leaves my bongs shiny and streak-free. It doesnt smell bad at all and it doesnt burn or anything when you get it on you. Even when it has a hard time getting in the nooks and crannies of my bowl, it still loosens it all ip and i just have to rinse it and go in with a q-tip, never leaves it greasy either since the “salt” is already in the solution.

Our favorite cleaner. It only takes a few minutes to clean and the scent is super groovy. Like tutti frutti bubble gum. The crystals make it easy to “scrub” the interior surface of the device.

Great stuff for cleaning pipes.

Formula 420 works so good! It really does only take a minute or two and the gunk comes right off your pieces. It smells good so you don't even notice how nasty your glass is. If you are cleaning a bong or bubbler, you can pour this product right into your piece. Make sure you give the bottle a little squeeze to get some of the salt out of the bottle. If you don't make sure you shake this up, you will end up using a lot of the fluid and end up with a bunch of salt solution in the bottle. Shake it up often and give it a squeeze. When it is in your piece, plug the holes with your hands or fingers and shake it around. If you have thick junk on your piece, you can get some tools and scrape it off after using this solution for 30 seconds. It loosens the chunks up and they scrape off very easily. After you scrape the big chunks, keep shaking it around. You can put your smaller pieces in a ziplock bag and shake those around in there. The solution gets gross looking but you really can use it for quite awhile-you don't have to use new solution just because it's gross. Thankfully, it can be black and chunky but it doesn't smell bad. This solution overpowers any gross smell from your pieces. AND it's non toxic!! When you're done cleaning, just give your pieces a good couple of rinses. and dry. When you can't smell the solution anymore, you are done rinsing. At this point your hands might have some funk on them. You can use the solution the get the stickiness off your hand or I like to use lemon essential oil. That works great for removing stickiness. I put several drops of lemon oil in the palm of my hand and run my brushes through my palm to clean them. The price here on Amazon can't be beat! I bought one bottle in a head shop and spent like $10. You get 3 bottles for $17 here. Great price! I will never be without this stuff again!

I decided to switch to Formula 420 Glass Metal Ceramic Pipe Cleaner from the Ooze brand after reading reviews and seeing the high ratings, and I’m so glad I did! This cleaner works amazing on the first try — it gets rid of even the toughest residue and buildup, leaving my pipes sparkling clean. The formula is incredibly powerful and cleans both glass and metal pieces without any effort. The only downside is that Formula 420 is single-use only, unlike the Ooze cleaner, which can be reused. I was a bit disappointed at first, but the Formula 420 does such a better job on the first cleaning, I don’t mind using a fresh batch each time. It’s super quick and effective, saving me time and effort compared to other cleaners. If you’re looking for something that works immediately and thoroughly, this is the product to try. I’ll be sticking with Formula 420 for all future cleanings, and I will definitely repurchase when I run out. Highly recommend it for anyone looking for a powerful, easy-to-use cleaner. 5 stars!

Been using Formula 420 for years. I pour it directly into my bongs -- just a few drops -- add hot water, seal off the ends with Hemper caps, shake vigorously until the salt gets foamy, wipe off residue with a brush, and rinse. Voila! Good as new, again. For smaller glassware, i use a ziploc. This does the job, within reason. Deeply-encrusted gunky resin may need to soak a bit; for that, they make Fomula 410, which they may have renamed Formula 420 Clean N Soak or something like that. You will need bottle brushes to wipe away residue once it's loosened up. For bowls with honeycomb screens, use a paperclip and an isopropyl alcohol pad. This stuff is real simple, rubbing alcohol and epsom salt. Hot water "activates" the salt when shaken. It works near-instantaneously on light to medium-duty tasks. And a little goes a long way, so it's fairly economical too. \

This stuff works great and has a pleasant smell. It makes the parts look like new very easy to use.

this stuff is great

Super easy to use without a super strong chemical smell, Simply soak whatever you need cleaning with a bit of hot water and the Formula, after 10-15 minutes all grime is gone, Like new! Will be purchasing again!

I always thought these things were a complete gimmick. Boy was I wrong! My fiance's NASTY vase had been stinking up our place to high heaven! Nothing would get the flower residue out of this vase! I mean NOTHING! I tried vinegar, soap, hot water, ketchup, salamander pudding and even isopropyl alcohol! Well on my knees, as I cursed the flower gods, I decided to give in and try a commercial product. Fellas. I put half a bottle of Formula 420 into the vase, shook it a bit, and the filthy black flower residue MELTED away in about 20 minutes with periodic shaking. This stuff is the best vase and/or flowerpot cleaner I've ever used! Now we can present our petunias proudly! And without that dirty Marijuana smell!

Works well. Don't need much to clean a small bong..

Works so well. Will clean even the dirtiest item. Just put the item in a container with this stuff, let it sit for 10-15 minutes, rinse with cool water and place back in solution again if necessary. It shouldn't take more than 30-45 minutes. It's reusable as well. Even when this stuff has been used 3 or 4 times it still cleans well. I threw out after 4 uses to buy a fresh container but you could probably use more than that.

Cleaned bongs very well. Much less vapor than alcohol based cleaners. I cleaned my bongs by plugging the stem and filling them to the top then leaving it over night. Afterwards cleaned my pipe with the same liquid by pouring it into a Mason jar. I've used the same cleaner about 4 or 5 times now and it still seems to have a couple more uses left.
