Invisible Glass Stripper Water Spot Remover, 4 fl oz, 91411 | Cerium oxide glass polish removes hard-water spots, road film and old coatings from windshields

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.

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.

All the included items work. Just wish the polish made my clubs look like their video. Might be technique, but cleaning out the grooves was eye opening.

This is the best cleaner ever. Every time i cleaned my windows i always had streaks on it . Id rewash the window and still have them. Ive used different glass cleaner different towels , newspaper, paper towels of every kind and rags madeof every kind. Ive used the invisible glass cleaner a yr or so it was better but when i seen this product i decided why the hell . Its amazing. I followed the instructions and it took all the build up on the window off all of it. I assume it was all the stuff in the air and the residue from the soap and wax from car washes. Anyway it goes on like wax pretty easy then wash it off with water . I dried the windshield and then used the window cleaner and it is very clear now. Its also much easier to now. I done the inside also and used a few wet towels to take it off. No more streaks or smears. It also beads rain really good also. This bottle should last awhile . Its not something you have to do all the time either. Id give it an A+.

It works, but you need to wipe it many times, and it will be better if you use a polisher. The principle is the same.

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.

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.

This worked amazing to strip the glass. I used this to fully strip the windshield before coating the glass.

they are not moist enough pratically dry.overated for the outragous price will never buy them again
