91411-6PK Glass Stripper Water Spot Remover Kit – Cerium Oxide Based Auto Glass Polish for Windshields, Hard Water Spots, Road Films & Old Coatings – 4 Fl Oz (Pack of 6)

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.

it got up some pretty serious water spots off my CRV windows. I tried cleaning vinegar, magic eraser, and a razor blade. Nothing worked. This with a little scrubbing washing, scrubbing washing, repeat, did the trick. Would recommend.

Very usefull product to remove oil film on the windshield, which becomes clear without water drops.

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.

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.

Worked like a charm! I purchased a vehicle last month and noticed a lot of water spots on both windshields. I lived with it for a few weeks then decided to do something about it. This product works as described. One tip: make sure you wash off the film as it will stick to anything including paint. Run a hose to get it off and I used my hands to get it off. I missed a few places and i'll get to those later. But glass is crystal clear now. I'll use the remaining on my other cars. May even buy a bigger bottle.

Had some sort of oil glase on front windshield, tried other products to get it off, this stuff is no joke,took maybe 20 min for both sides and just used a bucket of water to rinse off. new blades front and rear of a 20 Grand Cherokee, really nice job removing the oil and no skipping. well worth the price. I would use a hose to rinse off (just too lasy to drag it out front)

Product works well to remove water spots off vehicle windows to give it that crystal clear, new finish. You can treat your windows several times for the size bottle you get and should last a year or two depending on your environmental conditions. It doesn't have a strong scent, but will recommend you wear gloves while applying. Do it in sections and you will be fine.

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

Waste of money

The Invisible Glass 91411 Glass Stripper Water Spot Remover Kit works well for removing tough water spots, residue, and buildup from automotive glass, leaving the surface clearer and smoother. It noticeably improves visibility by stripping away old coatings, waxes, and oils that regular cleaners often miss. One downside is that it requires some manual effort to achieve the best results, especially on heavily stained glass. Overall, it’s a powerful solution for restoring clarity to windshields and windows. 🚗✨
