I like to clear up a small misconception first. There are several YouTube and TikTok videos showing this style product being applied to a glass surface and then a low pressure high volume hose is dumping water on it and it produces no sitting water where the application was made on the windshield. It shows the water just sliding off. There is very limited directions with this package and product. It doesn’t really say how long to leave it on and any other instructions that might inhibit or not allow this product to work. I went ahead and applied and let it dry and removal is as simple as using your windshield wipers, a car wash, or just a little bit of window fluid and cleaning it off. The very next day after applying this I used the hose and blasted the windshield. Even during the worst of it, I didn’t really see the water beading up on the glass, pulling up, I could hear the water hitting the windshield, but there was nothing sticking on there and it was good visibility. I was extremely impressed. A few days later, it rained and none of the effects that I had previously were noticed. I had to use my wipers And other than the glass being clear. It was almost like I did not use this product or none remain. I am not big on companies that embellish their products or flat out lie the buyers hoping for a quick sale on a junk product. I checked the description of this product again, and the majority of the entire description is telling us this removes oil and other contaminants and creates a clear looking glass. We are going on a month now and my glass is still clear. Although the water doesn’t magically roll off and create a situation where you do not need wipers anymore, but the windows themselves are perfectly clear with no oily residue. That alone is very impressive. When I weighed the entire results and reviewed the description again I felt this product is almost 100% as described. My windows are still clear and that is the main reason for forgetting it.Because of that I am not removing any stars and I will continue to use this oil remover to keep my windows clear. This product easily earns five stars.
