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

Works as stated. No scrubbing and no leaving residue. Easy to use.

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!

This is the best solvent I’ve tried. Removes everything by just soaking, if you prefer. I’m sold on the soak n rinse version. It’s excellent

So fast and very good!

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!

These do their job perfectly with a little bit of effort in the shaking department :)

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. \

I'm always impressed with Formula 420 Glass Cleaner, and it's strong enough to be used several times before discarding. I use a funnel to pour it back into the bottle once the bong is clean. For cleaning glass bongs, this is the best I've tried. I use another brand for soaking bowls and down stems overnight, but with the to help scrub the glass as you shake, this is the best for bongs. It makes the process incredibly fast – just a few good shakes, and even stubborn residue disappears. The efficiency is very appreciated. I've set it up for auto-delivery. It ensures I always have it on hand to keep my glass sparkling clean with minimal effort. If you're looking for a cleaner that delivers fast, pristine results every single time, look no further. Highly, highly recommended!

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.

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.

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!

Both bottles nozzles broke during delivery dissapointed with the packaging. But product works great overall just rinse with hot water before using to loosen the rez.

I was a little more excited for this product than I should have been but I’m tired of the tedious cleaning of the stem & bowls from my bong. I put the two items (stem & bowl) into a ziplock baggy and covered them in this solution. Almost 6 hours later, and occasionally giving the baggy a little shake, there was still a layer of resin inside both items that I needed to scrub out with a brush. They weren’t even all that dirty, they’ve been much worse!! Based on the reviews I had really high hopes for this stuff but it just didn’t deliver!!
