Got this for my new Kia Seltos because the previous owner did not know how to clean their windshield. Works like a charm, I can see perfectly through all of my windows and they've perfectly clean. Took it through a week's worth of rain and snow and I only reapplied at the end for redundancy. This stuff works, and it works well. ...Here's the deal though, unlike the other reviewers on here you have to actually know how to buff a compound. No towels, no ripped up t-shirts, you NEED microfiber auto cloths, buy a pack of 20 from this website for like 5 dollars. Here's what you do to avoid improper application-induced psychosis: 1) Apply a spray for every 6-12 inches depending on your window. ( For me, 4 sprays on the front, 2 per window.) 2) Spend a bit wiping down your window with one side of the microfiber, you should start to see streaks build up like you're waxing your windshield. Give it like a 30-50 count on each part of the glass. 3) Using THE DRY SIDE or ANOTHER MICROFIBER CLOTH, vigorously make small circular motions across your entire window. Your goal is to really break down those streaks until they start to disappear a few seconds after you make a pass. If you're using enough elbow grease this shouldn't take longer than 30 seconds. 4 (optional) ) IF AT ANY POINT your cloth becomes too 'wet', or saturated with cleaner, get a new towel. The wet side is full of cleaner and will stop you from working to a shine because you'll just keep applying more cleaner. Spoiler Alert: This is what the instructions on the bottle tell you. Follow this method and you too will understand basic car maintenance better than several lowly Amazon complainers. Read more

I purchased Rain-X cerami x glass cleaner for glass shower doors and it works great. I have now used it on a windshield, however I see no reason why it wouldn’t work just as well in that application. Rain x keeps my glass shower doors clean and streak free better and longer than cleaning alone. Also it has a really nice scent to it, that I was not expecting. I have also used it on mirrors with fantastic results, keeps them clean and mostly fog free following a shower. Read more

I really wanted to love this product, but streak-free requires an act of God. I had to purchase a detailing, buffing cloth to eliminate fogging/streaking. Then I have to finish with dry paper towels. It is excellent repelling water, but it's a minimum of 30 minutes to clean glass. Read more

Leaves a fog like film and is extremely difficult to wipe off. Looks clear until you drive into the sun and then streaks show up along with wipe marks. The original Rain-X yellow bottle was a lot better and I will go back to that one once I figure how to get this one off my windshield. I wiped at least 8 times and cannot get it off. Read more
