ALL NATURAL Formula 420 Pipe Cleaner - Cleans - Glass, Pyrex, Metal, Ceramic 16 Ounce

Prior to using this stuff, I used Isopropyl Alcohol and salt to clean my glass. I would usually let it soak over night and then shake it for about 10- 15 minutes (I would obviously do it in increments). Most of the left over material would come out but there was always a few spots that I really couldn't get to. After reading some reviews, I decided to buy this and give it a try. I can say that this is one of the best purchases I have ever made. This stuff will make your glass look BRAND NEW again. I also use it in my Ashcatcher (extremely hard to clean), and cleans it like the day I got it. The best part about it is you don't have to throw away it after your done. I've reused the one bottle I bought about 5 times now, and it STILL cleans it just the same. This is what I do: 1) SHAKE THE BOTTLE VERY WELL. This is important because there are small crystals in the liquid that sink to the bottle. You want those in your glass to clean all of the stuff off the sides. 2) Pour a decent amount into the glass. I usually fill my the beaker of my water pipe about half way 3) Let it sit for about 2 minutes to soak 4) Plug the holes and shake until clean TO REALLY GET YOUR MONEY'S WORTH: 1) After use, GET A TUPPERWARE CONTAINER (w/ lid) AND SHAKE ONCE MORE to get all of the crystals back into the liquid and quickly dump it into the tupperware contain. You want to save as many crystals as you can because these are what really clean it. 2) You can even go as far as setting your glass (opening down) on a paper plate, and leaving it until all of the crystals are out and dump into the tupperware container with the liquid (Yes, I do this). You can put it all back into the bottle, but that's kind of a pain. Tip: As to not dirty the liquid too much, RINSE your glass out good with water before you use this stuff. You can clean slides and downstems with Isopropyl Alcohol. No reason to waste this stuff on parts of your device that are easy to get too.

I ordered this because I ran out of pipe cleaning fluid, and seriously needed some more so I can thoroughly clean my grinder, pipes and bongs. I used the Formula 420 cleaner as directed, and it powered through most of the residue, and it even leaves your glass or grinder smelling better too! If you're a sesher and you need to rigorously clean your pieces, then THIS is the cleaner for YOU!!!!

This stuff is pretty good for just a minute of shaking and not having to deal with the alcohol and salt combo I usually used. I put before and after pictures up. That was just using this 420 cleaner and shaking for about a minute I'm sure if I did it again I could get the last of the residue but this is good enough for me. It cleaned better than the salt and alcohol I used before so I'd say its worth the money. It also has a really nice citrus smell.

I have used every glass cleaner out there and this is THE BEST one. You can literally watch your glassware go from black to brand new. Through experimenting I have discovered that this little bottle can really go a long way if you are willing to sacrifice a tupperware/pyrex dish to be your permanent cleaning container. For glass pieces small enough to fit in this container you can use the whole bottle and keep it sealed for future use. I simply put my piece in, squeeze the whole bottle over it making sure the crystals get inside chambers and then let it sit for 5 minutes. I give it a gentle shake back & forth in the container then leave it for 30 minutes-1 hour depending on how dirty it is. Next, I'll wear a pair of protective vinyl gloves and use a qtip soaked in the solution to get in crevices/holes and scrub them clean. Lastly, I run the piece over HOT water and use another qtip to finish detailing it. With larger pieces like a water bong or hookah I squeeze the whole bottle (or as much as it needs to cover up where it is the most dirty) and let the piece sit for an hour, shaking it every 10 minutes to let the crystals "scrub" away where you can never reach with your hands or another cleaning tool. Once it's clean enough I empty it into a tupperware/pyrex container (try to get as much of those crystals out before rinsing) and then run through HOT water, continuously shaking to rinse completely. All my local head and pawn shops used to carry 420 Cleaner but have stopped over the last 3 years, which has forced me to order though Amazon now (I don't mind, but I actually wish they would make it a Subscribe & Save item) You will not be disappointed with this cleaner!!!

Used it the day it came within minutes of the package arriving. Cleaned my new glass piece with it and it looks like new! This stuff really works and smells amazing. The bottle was slightly wet when it arrived so it seems there may have been a leak but it wasn’t very large and the bottle was still sealed and full. The seal was difficult to peel off and had to be punctured instead. Really cleans in one minute as advertised! Worth every penny.

Works great for cleaning smoking products and ash trays . There is a smell that I kinda don’t like but it isn’t too bad . You need to shake the bottle so the liquid’s consistency is thick- ish. The bottle is a thicker plastic . There was no leakage upon shipping or delivery . The cap seals well . Do NOT get in eyes or mouth . This is a cleaning product do not invest in anyway . It works well . I would recommend watching it with warm water make sit smell stronger . A reliable way to clean up tarry ashy messes for the smoking population . I used this to clean my glass ashtrays after a party and it worked great on the glass . It may discolor clothing , I am not sure . I did wear plastic gloves to be safe . It might be sensitive on skin to some ,please be aware . Also not too good scent for those sensitive to cleaning smells or those who get migraines with smell triggers

Works great with glass pieces! Highly recommend!

I never write five star reviews because a five is above and beyond. Please take that into consideration as you read:) The bottle arrived in a package with some other items I orders. Somehow the contents either of this bottle or another had made its way out of the bottle and all over most of the rest of the order. That's the worst I can say about it. The scent is almost identical to the Orange automotive hand cleaner. The color is almost a neon yellow-ish green. Like Mt.Dew but not clear/translucent. Its performance was above and beyond anything I have ever seen. I followed instructions to a T and my glassware is cleaner than I have ever seen it. It was a used gift from someone. So I had never seen it brand new until I took a minute and thirty seconds out of my life to use this. Its simple to use. Its easy as shake the bottle, pour the fluid, shake the item to be cleaned for (it says 60 seconds but I was done in maybe 19 or 20, no joke.) It cleaned crud so thick I couldn't believe it. I've used 91% Isopropyl Alcohol and Rice soaked over night, shook til my arms fell off and never made a dent. Less than thirty seconds after I started using it I wanted to see what else it could made disappear. The first thing I could think of after using this, besides OMG this is amazing, was I wonder if I could use this to get the hard water spots off of my windows. Its that good! I haven't tried it. But if it works I have to find a way to order gallons of this to clean my windows and not break my house cleaning budget.

Llegó chorreado y prácticamente a la mitad de la botella.

I was so excited to see formula 420 natural finally offered again on amazon. This is by far my favourite cleaner. The crystals make it very effective and the smell is not overpowering. TIP: Make sure you give it a really good shake before you use it so you can get the crystals mixed in.

Very impressive product!! I've only really soaked parts in plain rubbing alcohol which took overnight. I laughed sarcastically when I read this cleans in 60 seconds and thought, ya right but it really worked!! The glass parts and my grinder looked new in only a minute.

This stuff is great! I wasnt terribly optimistic but was pleasantly surprised. It got all the gunk off my bong and left it looking sparkly. You really dont need much product at all

Cleans good but kinda burns your bare skin
