Formula 420 Glass Metal Ceramic Pipe Cleaner, 12 Fl Oz (Pack of 4)

I really like this stuff! It doesn't smell as strongly as the regular formula and it works just as well. My only complaints are that one of the bottles in the 3 pack always seems to leak and it may have a little too much aggregate, but it gets my glass clean!!!

Been buying this particular product for several years I can’t count how many bottles we’ve purchased, but it is a fantastic product that works well and quickly with no odor or residue

Use daily, takes minutes to clean even built-up gunk.Quality customer service promptly resolving delivery issues.

420 has been around well my birthday is 4/20 so it's been around as long as I've been around LOL and that's a long time. But no back in 1980s in high school we used to use this stuff to clean our stuff then and here it is today they have different formulas but if you're just cleaning bong glass Pyrex This is highly recommended works every time gets Everything clean. Now if you're using a rig and cleaning oil, I would get the 710 formula.

This stuff is magical. It made my husbands bong dirty to clean in seconds. ! I love it. It smells so good, and overall makes the appearance look so much better. I love not having to clean it for hours

It really does clean out glass quickly. When I put my hand over the holes to shake the liquid, after a minute my hand got a little tingly where it covered the holes. Make sure you wash your hands after and thoroughly rinse everything out. It is really effective though and has some kind of sugar like substance that helps clean as well. I would recommend.

Good product

This cleans everything EASILY! No more alcohol and salt!

After over a month of trying to clean my bottle of stains I decided to try this stuff, I was amazed at how well it has cleaned my bottles to the point that they sparkle, I did not expect to use almost an entire bottle of this product in order to clean just 1 of my bottles but I did have to use a lot. Overall amazed with the results!

Works really well & super quick!

Three bottle is about exactly enough for the month. I clean roughly every two or three days, change my water at least once a day though. Stuff works like a charm and a smells fantastic.

It’s ok. I’d technically give this a 4.5 because if you’ve been cleaning your bong regularly (after about ever quarter of an ounces worth is usually when I clean mine) it does a great job. My problem was I was trying to clean some old resin from old pipes and it was basically useless for them, even when I enclosed them into a ziplock bag, kept it airtight overnight, still did next to nothing ever after instructed use with hot water. Repeated cycle for final clean. So it’s okay, and honestly I feel better using this for cleaning my bong over isopropyl (which has better uses than bong-cleaners right now).

Don't drink this please. No idea why it even has a flavour factor. But I might as well be the one to warn you. Not edible. Very not edible. Works some what on residue from cannabis on glassware. Better this then the regular formula just need to shake more aggressively with this brand.
