This review is for Invisible Glass 91411 3.38-Ounce Glass Stripper Kit. This kit is supposed to remove water spots, road film, and coatings (such as polishes, waxes, hydrophobic barriers, etc.). I purchased this because I wanted to step up my game on cleaning my car windows and for getting better results with my windshield wipers and hydrophobic barrier applications. Invisible Glass Glass Stripper was one of the top recommended based on professional reviews, consumer reviews, and application/results videos I watched. The application was very easy, and the included applicator sponge is of good quality. I may have used more of the compound than I needed to. I mention this, because the bottle is pretty small. I probably used up about half the bottle doing all the windows on my car. The directions say to use Invisible Glass Glass Cleaner before using Glass Stripper. The Glass Stripper is applied by shaking the bottle thoroughly and applying the white liquid/paste to the sponge applicator. Then use small circular motions to scrub the glass in overlapping motions as to not miss any spots. Be careful not to get this compound on to anything other than glass, as there are elements in this compound that are abrasive. If you do get any of the compound on to anything else, such as paint, use generous amounts of water to get it off. Do not rub the compound off the paint, as you will scratch up the paint. If you do have to use a towel to whipe the compound off of paint (or other surfaces) use a very wet, clean, microfiber towel, and carefully lift the leading edge of the microfiber towel away from the surface as you wipe. The compound is white, so it is easy to see your application, and it dries to a white chalky haze. The instructions then say rinse it off thoroughly with water. If you do this, you want to make sure you are very thorough in rinsing all the compound away and off the car so that there is no residue left on the glass or car. I did this in my garage in winter, so I used a damp microfiber towel to wipe away the compound, followed by a second damp microfiber towel to remove any remaining compound. And I followed that up with a clean microfiber towel to dry off the windshield. Doing this method worked very well, and I did not have any water run off of the glass onto anything else. The water droplets stuck to the glass very well. Which means this Glass Stripper must be effective at removing coatings, since I had an application of Rain-X on my glass prior. However, I did notice that a number of water spots that were on my glass (particularly the rear window, which gets the dirtiest) remained. So, Glass Stripper was not as effective at removing water spots as I had hoped it would have been, but it is possible that the remaining water spots could possibly be etched into the glass. Here is the overall process I did for my car windows. I washed the windows with car soap and water using a microfiber towel, then wiped the soap off with a damp microfiber towel, and I dried the windows with a microfiber towel. I then did two cleanings with Invisible Glass Glass Cleaner and a microfiber cloth followed by an application of Glass Stripper. After this I did an application of SOFT99 4146 Ultra Glaco Glass Cleaner (it's called glass cleaner, but it is actually a hydrophobic barrier coating (like a Rain-X)). The overall results were excellent. There are additional steps that can be done to clean the glass even further. One thing would be to use a high-speed buffer with a foam pad and a glass cleaning compound, such as Glass Stripper. You can also clay bar the glass in the same way you would clay bar the paint. I have seen videos of people using ultra-fine grade #0000 steel wool to clean glass as well, but you would need to be extremely careful that you get the ultra-fine grade, use gloves, and don't touch anything that is not glass. On a side note, the newspaper trick is great for no lint, but then you wind up with ink on your hands and possibly on the car if you aren't careful. A good quality microfiber is the way to go, and yes, there are big differences between microfiber brands out there. I have used some that just don't clean and leave lint, to others that are so effective that they can actually clean just with water.

Made a big difference on my side view, windshield and rear car windows with limited time and little effort. Glass had BAD water spots that dried off in hot sunlight. That baked on stuff over a couple years until I decided that the problem had gotten to much. On the box there’s a smart phone camera link with a demo “how to use” video. Make sure you have those sopping wet micro fiber towels to wipe off the glass stripper from the treated glass. You also need to apply a glass cleaner afterward and not leave the glass completely bare. Simple, best to take your time and do in sections then inspect and hit the any sections of leftover spots. Worked good easy to use. I do suggest wearing around the house shirt/pants for the task as it’s always possible to get any of this type of product on your clothes by accident.

It worked very well. Removed stuff that's been building up since the car was new. The glass is clean and clear. The oily film is gone. I can see great. I would recommend it . Easy to use and affordable. It makes glass and mirrors look new again

I ceramic coated my car a few months back, and when I did the windshield, I messed up and left a gnarly high spot line down the middle of the windshield. I ordered this stuff just so that I can could remove the ceramic coating and more importantly, that line that was right in my field of view. This stuff worked fantastic, I was able to remove the ceramic coating on my entire windshield in about 5 min and reapply to perfection. HIGHLY recommend this stuff. Its cheap, safe (won't scratch your glass), works fantastic and you can probably do quite a few cars with it.

I bought this to remove water spots and road film, but after one use, my windshield looks exactly the same. I followed the instructions and used the sponge provided, but it just didn't live up to the hype. It feels like a lot of effort for very little result.

My wife was complaining about headlight glare, now we keep her front and rear glass windshield extra clean with this what about once a month. Glaire is not gone but she noticed a big difference. Also if you use automated car washes they leave a film on your windshield, this is very effective for keeping it clean.

This was a very smart and reasonable choice. The famous Japanese brands are just too expensive, but this one has a fair price and works perfectly. My windshield wipers used to have terrible chattering, but after using this glass scraper, they are as smooth as new again. Thank you!

My windshield had alot hardwater marks, wax type build-up that would not come off. At night the visibility was dramatically reduced due to the glare it caused. After just 20mins using the glass stripper the windshield was returned to like mew visiblity.
