Grunge Off Super Soaker 16.0 Fl Oz

Works better than anything else I've used. Reusable dozens of times, just pour it back into the bottle or strain it through a coffee filter if you want to get a little more life out of it.

A few things I've found so far after using the product.-- TIPS --- Has been used on a TI Nail without any negative results, I was looking for that info earlier, so hopefully that helps someone out.- Soaking is pretty quick, less than an hour if your piece is not caked with resin. It totally depends on how dirty the object is, but sometimes you can only soak for 15 mins, rinse and it's sparkling. However other times (stories below) I've had to sit longer than overnight and require scrubbing/abrasion.- Requires heavy rinsing with water- Safe so far to use with a cheap tupperware container (just the super thin cheap ones) and it's survived multiple uses.- Seems to work better with oil resin than the resin from burning medicinal herbs. I think the reason is that the oil resin doesn't create a crusty layer it's always somewhat viscous and just sheds off the glass w/ Grunge Off.- Will not dissolve plant matter very well. Think of things like vaporizer bowls that have a lot of leftover actual plant matter. You want to scrape this thoroughly before soaking--STEPS--[] IF a small piece (bowl, pipe, downstem, nail, small bubbler, etc):1. Put your dirty products in the bottom of a container container, pyrex or tupperware (don't use the tupperware for food after).2. Pour product in, ensure it covers the object(s)3. Inspect carefully for air bubbles, twist and manipulate (maybe even shake) objects to ensure the product is in every nook of the object.4. Covert it and come back later, usually less than an hour later and pull out the object, returning any residual liquid to the container.5. Rinse thoroughly, repeat if necessary.6. Return product back to original bottle, strain (coffee filter) if necessary[] IF cleaning a water pipe:1. Using a paper towel, twist it up thin enough so that you can stick it into any opening (downstem hole, etc) that you need to plug up.2. Cover the paper towel with plastic wrap, just a small piece is needed3. Shove that into any opening you need to plug up4. Pour product into piece through mouth opening5. Inspect the seal you made in step 3, allow some air through if you need the product to completely fill the interior of the water pipe.6. Wait, depends how dirty, usually less than an hr. You may need to give a bit of extra care to the spot you plugged up since it may have not gotten touched by the product.7. Pour out product, save it and return to original bottle. strain (coffee filter) if necessary8. Rinse thoroughly. Repeat if neeeded---PROS----It works, unless you have an especially dirty object (see below), then you will effortlessly get it sparkling clean.-It's completely reusable, even if it looks dirty. If used for medicinal herb resin/glassware then you will likely get ash.-When it comes to oil resin, it just melts away. Faster than you probably would expect. Stick some grunge off in an essential oil rig and come back 30 mins later it's spotless.-Doesn't seem to be too corrosive. I've gotten it all over my hands, some went down the sink, some got on the countertop, etc and no negative results so far. Also used it on a TI nail without any issues.- No shaking (again, there are special cases with very dirty stuff, as explained below)---CONS---- Needs heavy rinsing -- Grunge Off is somewhat soapy, honestly think of it as the consistency of motor oil, or "personal lubricant" -- and needs to be rinsed with water thoroughly. It will even foam up when rinsing. If you have a product that (for whatever reason) you cannot thoroughly rinse with water, this won't work. ISO will naturally evaporate, so as long as the reside is wiped off, the residual alcohol will just evaporate, so just keep that in mind.- It will still struggle with very problematic objects. Do you have a really hard to reach area that has 2 year old caked on resin deep in the downstem of your small bubbler tobacco pipe? Is there a spot on your pipe that gets blasted with hot ash and has created a thick caked on ash layer fused to the glass over the last decade? Well, that thick layer of gunk won't break up easily, even with grunge off.I actually had one piece that had maybe 6 years worth of just old medicinal herb resin in it, the only cleaning it had was using a paperclip to clear out airflow blockages. This wasn't easy for Grunge Off, but it eventually worked.What I've found with these crazy dirty objects is that you'll soak an object, rinse it, and there is just one small area with stubborn spots of caked on ash/resin that the product just can't break through and it does requires extra long soaking and scraping. I think something with crystals (ISO+Salt or another product that has crystals) would do a better job in those hard to reach areas that just need crazy scrubbing.

Sheldon black glass turn me on to this does everything you need it too. Does not hurt the labels or gold foil

Works fine.

Work's awesome.

This is the #1 cleaner I have tried. After 10 years of buying more expensive cleaners and going through ISO the last bottle I had of this lasted me 3 months of cleanings. I am a “heavy” user so while the cleaner will turn black and get thicker, it does still work until there is no liquid left. It doesn’t do any damage to scientific, soft or colored glass. I don’t use it for quartz but for rigs/pipes it is my #1 choice.I pour some in the glass to be cleaned and plug the ends and shake it to get the cleaner all over. Then come back maybe 2 minutes later and most crud will rinse off immediately in hot water.For smaller items I set it in a water glass or jar and cover with grunge off. For carb caps that you can’t shake around this is a must have.

It's great. Soak item in it for a day, easy to clean after that. Just like new. Great item.

I've been using this for years now and it really gets into all the hard to reach places of any glass piece. Just let it sit for a few hours, rinse with hot water, and just about anything will come off! The smell is strong but clean. I recommend NOT using this on any type of plastic. Highly recommend!
