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

Grand Master soak and wash worked and smelled SO good! Also came in a huge bottle. My glass was very dirty so I left it over night for 24 hours as suggested and let me tell you. At first it seemed like nothing happened until the pour. Started pouring out the soak and gave the glass a few shakes. All the gunk started to fall right off like nothing. I ran water through it a few times while shaking and ended up with a brand new piece at the end. Almost forgot it had color to it. Nothing like a fresh hit on clean glass!! ! 5 stars and will recommend to all my glass smokers

Work great. I soaked overnight and it cleaned up really great! My glass was super dirty and it looks brand new. I recommend

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.

This stuff does work well... can take several hours to clean but it does get the job done. If you have extremely stained pieces it might not work at all so it by no means is a miracle worker. It does require scrubbing too if you have a really stained piece but after a couple passes and some light scrubbing I did manage to get my bubbler clean and after a LOT of elbow grease I got a Bong from over a year ago I had in my closet from black at the water level to almost perfect other than a couple scratches/vague resin here and there. If you don't want to scrub it I'm sure just plugging the pipe and leaving it overnight might work but this method is indeed time consuming so I'd recommend this for a time where you're not busy with anything else. It works, however there might be a feint waft of a residue smell left over after cleaning which is strange because the solution itself has a VERY overpowering sweet bubblegum/fruit punch smell and a prominent pink color. Give em points for general cleaning and reusability (side note: be sure you have a funnel if you want to save this stuff) because that's what counts the most but it is time-consuming and somewhat false advertising for sure.

Some of the best product I have found and used. Looked like new when done. Soaking was the ticket. Great will buy again and use often

I do wish I had taken before and after pictures. As i had not cleaned my pips in months. I did have to leave them over night but they washed out the next morning looking amazing like brand new. I will say leaving them to soak overnight gives you the best results when there really bad. But if your somone who likes to clean there pipes every couple weeks then letting it soak for the 1 to 3 hours as the directions say it does live up to what is advertised. 10 out of 10 try it you wont be disappointed.

I decided to try this product due to the fact it said so shaking or scrubbing. since almost all other products i've used you always gotta shake n scrub a bit. Unfortunately it was a lie. I used the product to clean 2 of my pieces both fairly small one a glass bubbler and another a glass pipe. at fist i had them soaked in the solution for about 2 hours, and when i took them out yea it cleaned them a it but there was still whole bunch of resin everywhere on botch pieces mainly the bubbler. so i did what the instructions on bottle said to rinse with warm water and re-soak them in the solution if it still needs more cleaning. This time i decided to just leave them fully soaking overnight since i thought maybe cause i use those pieces to smoke daily and they more resin built up than usual smokers, it might take a longer time for the solution to work properly. The next day in the afternoon i decided to check my pieces and to my surprise nothing major happened it was still dirty and still has a bunch off resin everywhere. when i rinsed them of with warm water , it cleaned it a bit more but still dirty as hell. i already had another piece i've been using and i hate scrubbing or shaking to clean my pieces which is why i decided to use this product, so i decided to not lose hope.! i threw away the old Zen master solution i had in my container i had been soaking my pieces in and to add the rest of the bottle in with my pieces and let them soak in there for about 1 week. I was thinking surely after 1 week been fully soaked no matter how dirty it should work right?? Well it didn't same ole scenario as before it clean it a bit but not fully till dirty resin and what not. So i just decided to scrub them with little wire cleaning kit and shake them in a ziploc bag with some solution and that did the trick! I HAD TO SCRUB AND SHAKE!!!!! I did noticed when i was scrubbing it was easier to clean probably since it was soaking for 1 week straight. I'm giving it 3 stars due to that i guess it did clean my pipes in the end & i did like the way the product smelled very soapy clean no chemical smell, but it didn't perform as it stated in the description.

I have tried many different pipe/glass/resin cleaners in my day and this is one of the better ones. No offensive aromas. Works rather quickly and comes somewhat inexpensively in a large bottle. I have a bubbler that despite changing the water almost daily, still gets covered in resin. I simply plugged the mouthpiece and carb, and filled the bubbler with 4-5oz of the cleaner. Put that inside a ziplock bag and went out to dinner with my family. When I came home, I found that the bubbler had tipped over and most of the liquid had slowly leaked out of my make-shift plugs. I have no idea how long it had been upright or not, but I pulled it out and ran hot water through it for a couple minutes. Much to my delight, all of the resin and canna-debris came right out with just the force of the running water. Now it looks brand new again AND I have a ton of this stuff left. I could have even saved the liquid I had in the bag and reused it, but opted to just go in fresh next time since I have so much left. Now that I know how well this works, I'll be buying the two-pack, which is a much better deal than just the one bottle.

Just poured some into the bong and left it overnight and my work was basically done right there. just cleaned it a little with a brush and done. amazing stuff . highly recommend.
