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.

I purchased the Invisible Glass 91411 Glass Stripper to deal with hard water spots on my car windows, and it did a really good job. The product is easy to apply and doesn’t require a lot of effort to see results. After using it, the glass looked noticeably cleaner and clearer, especially on areas where regular glass cleaners didn’t work. It removed built-up water spots and left the surface smooth and streak-free. I like that a small amount goes a long way, and it didn’t damage or scratch the glass when used as directed. It does take a bit of elbow grease for heavier buildup, but the results are worth it. Overall, this product does exactly what it’s meant to do. If you’re dealing with stubborn hard water stains on glass, this is a solid and effective solution. I would definitely purchase it again.

It is quite effective, really surprising. But don’t just follow the guide and wipe out with cloth, there will always be trace left and you can see it. It might be the microfiber cloth issue or my way of mopping. I found the best way to have it flawless is to flush it with pressured water.

worked amazing to clear a rav4 windshield of oil buildup and water spots that were affecting visibility during rain and at night. keep in mind this is strictly a glass stripper so it's recommended to apply rain-x or similar afterwards as a water repellent make sure the glass is generally clean before you start. shake the bottle, squeeze a bit onto the included sponge, and go at it with circular motions with some overlap. i left an inch or two from all sides of the windshield just to ensure i didn't get any on the car itself as it is abrasive. after this, rinse thoroughly with water and use a clean, dry microfiber cloth to wipe what remains. i threw away the 2 cloths i used for this as i didn't want the chemicals swirling around in my washing machine. if the process was done correctly and you try spraying water on it, the water should sheet rather than disperse unevenly after this, i applied rain-x and also switched out to new wipers. next time it rained, i tried it out and it's flawless. the water beads or just simply flies off the car at higher speeds and there are no oily streaks anywhere. i only did the windshield and there is enough left for me to do the remaining 4 windows and likely the back as well. can definitely recommend
