Formula 420 Perfect Pair : 1 Bottle Glass Metal Ceramic Pipe Cleaner 12 Oz. & 1 Bottle Soak-N-Rinse 16oz (2 bottles total)

I tried both of these and really liked both of them becuase they both cleaned really well.....the only thing I didn't like with the Black one is the smell.....the Red one (liquid is a dark blue), I feel, works just as good as the Black one, just with out the smell

It’s a good product. You’ve just gotta let it soak for a long time and then just rincé it with hot water. And these were 2 different pipes seized from resin.And they practically whistle

The quick one minute use one isn’t really “thick”, there are crystals in there though. Regardless it works absolutely amazing and cleaned glass faster and easier than ever before. I’m definitely buying more of this stuff. I would also recommend getting the 420 brand pipe cleaners or any regular pipe cleaner as well because you might need it for difficult spots.

I love the Formula 420 products, I only wish the crystals were separate from the liquid so you can add and keep the ratio of solution equal. The sent is ok, not overpowering. I didn't give 5 stars because my package reeked of cologne(I know it isn't the fault of the company).

Works well at dissolving resin. It takes longer than the label describes. HOWEVER, it does eventually work.

I soaked my bubbler for about 20-30 minutes Absolutely no effort. It rinsed clean and looked brand new! Wow! I’m impressed.

Best product to clean your pipes!

the soak and rinse works great the other so so

The presoak removes chazz!!!!!!Yipeeeeee!The cleaner is ok to,but I surmise it's just salt and alcohol with blue dye.
