Formula 420 Complete 5-Pack Cleaning Kit - All-Purpose Cleaner for Glass, Metal, Ceramic, Pyrex, Quartz & Silicone | Perfect for Bongs, Pipes, Dab Rigs & Smoking Accessories

The eco friendly bottle is absolute garbage. Used it like the regular stuff, didn't do anything, waited a few minutes to give it a chance. Literally nothing. Broke out the regular stuff, cleaned up as usual.So, it's an "ok" deal for 4 bottles, but for real, the "green" stuff is trash... So I'm not sure what exactly is eco friendly about that.Also, I didn't realize this when I ordered, but it's a selection of different sizes, some smaller than usual. Just so happens one of the larger bottles is the eco trash... So that's a bummer too.Again, it might still be a good deal, but it's your call vs going local if you can.All of these cleaners do their jobs extremely well. They just run out so fast when you use them regularly that the cost can be prohibitive. I can clean a medium-sized piece maybe a dozen times before I've run out of a bottle of the regular cleaner, which means it's costing a lot per clean. The directions on some are also not as clear as they should be. One of the bottles is supposed to be diluted before use while the others are not. Also if you leave a bottle sit for too long (lid shut) it will crystalize.All that being said, the stuff works amazingly well.cleans very well.It didn't stink most if these are nasty and difficult these were very easy to useEasiest and most effective cleaning method by far couldnt recommend enough. I’ve told all my friends how impressed i am with this product and so now they can enjoy this product tooLove formula420 so much!!Easily best cleanerThis product worked well for us. Made easy work of cleaning what normally takes a lot of elbow grease to get off. I used gloves and opened my window when using because I think it’s a fairly strong product. I will buy this again.left a residue that is hard to take off even after several washes hot or cold. made my bong hits very harsh for a little. wouldn't recommend. Also 30-40% of salt stays in the bottle as the flow control is no setup correctly to distribute the right amount of liquid to salt so when you pour you get either a load of salt no liquid or vice versa pretty annoying, dont recommend
