GRAND MASTER SMOKE 32oz Soak & Wash Glass Pipe Cleaner - Cleanse, Deodorize, Restore - No Shaking/No Scrubbing

Works really well. I was actually surprised how well it cleaned my pipe. I haven't cleaned it in soooo long and it had a lot of resin built up that I did have to let it soak for about 3 days. Now's it super clean and looks brand new. 10/10 recommend.

This cleaner is amazing! Easy to use just soak glass for a few hours or overnight and rinse all resin buildup just washea right out, no scrubbing or scraping needed. I just ordered more to have on hand. Another plus the instructiona say to pour the cleaner back into the conatiner after use and can be used again. 🏼

I've used other products in the past like 420, and Grunge Off. I'd say this competes with Grunge Off pretty well and leaves 420 in the dust. My percolator I keep relatively clean in general but man it cleared every bit of grime out of the shower head that goes down the middle which is usually the worst part. My bowl was completely solid black, it's double walled so all that clear space you see in the pictures does get filled to the brim with resin. I let it soak for about half the day and had to do a lot of manual shaking and bending a bobby pin to break up the bigger pieces so I wouldn't say this is a no shake or scrubbing cleaner but my bowl is weird in general so I think it really depends on the piece and how accessible it is to scrub. My bong itself didn't get fully clean, as you can see there is still residue and I shook the ever living piss out of it with grandmaster (dumped back into the container) then with hot water. (Note: I don't have a good brush to get into the chamber, I'm sure if I did I would be able to get it all.) Overall it did get about 95% of the grime off so I'm happy with it and will def use it in the future. If I had to rate all of the products I've used in the past: tied for 1st. Grunge Off & Grandmaster, last place 420 (I hate this stuff lol). It's well worth the purchase especially since it's reliable and does a pretty solid job overall. As a final note Grunge Off seems to be more Isopropyl alcohol based with some other ingredients and my issue with it is that if you get resin on your fingers you gotta scrub pretty hard still to get it off even with applying a little grunge off onto the spot that has resin. HOWEVER Grandmasters does NOT have this effect. I can simply dip my finger into it, run it under hot water, and it comes right off leaving my fingers clean feeling and not sticky at all. This is a weird but important thing for me as I absolutely despise having dirty hands in any way.

Honestly would be 5 star if it was better priced product as I'm pretty sure it's an all natural cleaner which is really nice as far as I'm concerned and hard to find. I thought it was a 3 pack from the picture because most of the products of this type at this price point are multiples but I was surprised to find it was a single bottle upon arrival and bought it at what I consider to be a high price when you can get 2 & 3 packs of different products that do the same thing here on Amazon.com for 12-15$. Also if your not creative with your bong in the sink and standing it up for optimal soakage when you use this product then you need a specially sized container that is just big enough for your bong so you can "soak it" meaning fully submerge it in the liquid. Only way to do that is either buy 4 bottles and fill your sink or buy a special container for your bong to soak in that won't use excess cleaning product to accomplish this. Or like I said above and get old with tilting your bong and filling it as much as possible... again this doesn't exactly get all the same spots as well as a full on soak will but it uses a lot less product so you get more than a single use from a bottle. So basically the product is pretty good in theory but unless you have the specially sized container for your bong to soak in which I didn't it's kind of a pain in the butt. Although it works so well and leaves so little after taste compared to other products I've used of similar types that usually leave after tastes for days that I had to rerate it and give it a fair shake.! Lol bong cleaner humor.! Ok folks hope this helped take care.!

Don’t usually leave a lot of reviews. But just have to say this stuff works really good. I just soaked my glass pipe in a Ziploc baggie for 2 -3 hours and then rinse in the sink. The thing looks like new! Highly recommended! And yes, my glass pipe is actually painted black around the bowl area🙂

Magic in a bottle! My boyfriends bongs gets nasty and it’s so satisfying with how clean this stuff makes it!
