Grunge Off Super Soaker Glass Pipe Cleaner, 16 Ounce (2 Pack)

Ive used this product for years. It removes gunk very well just by soaking- no scrubbing needed. It typically works pretty fast to start removing gunk but if youre product is extra dirty, I recommend soaking overnight. All you need to do in the morning is ring well with water and the appearance of your piece is like new. The best part is you can reuse it and it still removes gunk until the product turns completely black! Removability 10/10

Works well and is reusable, the only cleaner I use.

Works very well especially if allowed to soak.

Love this stuff works good

This is hands down the best product I have ever used for the purpose intended. It is a great product I have used for going on 5 months now. 1 bottle so far has lasted me 30 cleanings, 5 deep cleans (my glass was all black from use). I still use the first bottle but wanted more before I would ever run out. This stuff lasts forever. It works fast too, if you’re just cleaning off a regular piece it can get all the gunk off in an hour. My blackened pieces turned crystal clear as though brand new, in about 4 hours of sitting and soaking in the fluid. I would say this is worth every penny and while you can find it similarly priced elsewhere, it is worth buying through Amazon.

Quick and easy way to clean and sanitize your glass pieces. I’ve been using this product faithfully for a few years and it hasn’t let me down yet. Be sure to do this over a surface that “gives” as the product can leave the glass slick while rinsing. The scent is similar to the orange scented industrial soaps mechanics use.

Have a glass pipe that hasn't been adequately cleaned for about 5 years. (I tried ALL home remedies to no avail.) Grunge Off has it sparkling! It's non-toxic, has a pleasant odor, and is reusable--a winner all around!

the stuff works pretty well it smells kind of like a citrus orange flavor, it absolutely looks like it was watered down a bit though that was one of my worries looking at other reviews their was a hold poked in the seal so you could tell they watered it down but it still works great none the less my bong and bowl was filled with rez and i let them sit for an hour and that's all it took to get everything off they look brand new now so yeah its watered down but still works great somehow.
