Description

Invisible Glass 91411 Glass Stripper is a cerium oxide-based auto glass polish and water spot remover kit designed to deep clean windshields and automotive glass before applying rain repellent or glass coating treatments. More than a standard windshield cleaner, Glass Stripper removes baked-on water spots, hard water minerals, bonded deposits, road film, oil film, waxes, silicones, tar, tree sap, road salt, grime, and layers of old rain repellent coatings that can leave glass looking hazy or dirty. Use this auto glass water spot remover when ordinary glass cleaner is not enough. The cerium oxide-based formula polishes away stubborn buildup from windshields and car windows without scratching glass when used as directed. It helps restore a cleaner, clearer glass surface by removing the contamination that can interfere with wiper performance, visibility, and proper coating application. Glass Stripper is ideal for preparing automotive glass before applying a rain repellent, ceramic glass coating, or windshield treatment. The included foam applicator sponge allows controlled hand application. Simply clean the glass first, apply Glass Stripper to the sponge, scrub the windshield in small circular motions, rinse thoroughly with water, and wipe dry with a clean cloth. For use on glass only. Avoid use on hot windshields. Glass Stripper removes grade 1 deposits and grade 2 bonded water spots, but will not remove grade 3 etched damage without professional tools. Made in USA. Kit includes one 4 fl oz bottle of Invisible Glass Glass Stripper and one foam applicator sponge.

    • Excellent Glass Prepper for Pre-Hydrophobic Barrier Application
Size: 4 Fl Oz (Pack of 1)
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. ... show more

Works amazing! Easy to use. It got my windows spotless, took off some things I didn't even think it would. Followed up with some ceramic wipes, which I'd highly recommend for hydrophobic properties and to keep them looking this way!

    • It's best to use this on a clean dry surface
Size: 4 Fl Oz (Pack of 1)
If you use it when water is still on your windshield or windows after a wash, it's rather runny and not as effective at doing it's thing. When using it after those surfaces are just cleaned and dry, totally different. As you car detailers know, the rear area of your vehicle is almost always the most contaminated area because that's where all of the dirt, contaminants, and debris flies onto based on the aerodynamics of the vehicle. Even after a wash, you can see the outlined contaminated areas where the rear wiper blades don't touch. This product removes the visibly contaminated areas on your rear windshield for those that have rear wiper blades. Just on the border between where the blades wipe and doesn't. Tip: If you haven't used this ever, your windows might be really contaminated and may have to do multiple passes with this with more agitation to get rid of the stubborn contamination and oil film stuck to your glass. ... show more

    • Does a decent job with little effort
Size: 4 Fl Oz (Pack of 1)
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. ... show more

    • The only thing able to remove years of scratchy rubber streaks short of steel wool.
Size: 4 Fl Oz (Pack of 1)
Review Image by KMemz
My two vehicles - a Honda Accord and a Honda Element both hailing from the wonderful year of '05 - both have had really bad streaks on the inside of the side windows since the day I got them, you can clearly see them in this photo I took after the previous attempt to clean them out with foaming bathroom cleaner. It was truly impossible to clean, every single product I tried completely failed to touch it, and I really was about to concede that they were deep scratches until I got the bright idea to put an excruciating amount of elbow greas into the front driver's side window of my Element to fantastic success at the cost of my elbow feeling like scooter ankle for a week, a mistake I repeated in the Accord before giving up on that approach. It took two attempts, yes even this stuff struggled with getting whatever crud was on these windows out, but this stuff finally did eat through the streaking on all three remaining side windows of the Accord, and soon will be doing the same for the Element. It is a messy gel, it really likes to get everywhere, but considering it's picked up something I've otherwise been completely stumped by, it's easily worth risking it somehow splattering onto plastics and fabrics even despite your best care towards avoiding that. If you're using it on the outside? No-brainer, it will get the window cleaner than you might think possible, and there won't even be any risky splattering. ... show more
