630177SRP Cerami-X Glass Cleaner + Water Repellent, 23oz - Cleaning Effectively While Remaining Streak Free, Protecting Against Contaminants and Stains

It takes a little elbow grease to get it to dry without streaks, wear gloves 😆. Absolutely worth your time and effort. I live in the Pacific Northwest and this is a staple up here. It is so useful, I even bought a few bottles to give to my neighbor who washes cars for a living. You will need to reapply every season, but the spray on is hands down a better option than using the washing fluid variants, as those can plug the sprayer heads. And a little note, don't forget to use it on your side view mirrors too!

The product works as described. My windows are clear and rain beads right off

Great price works pretty good not quite as good as the original, but it still works at the same time, cleans the windshield.

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.

I bought this product recently and it was just as expected. It has been working like it's supposed to be and I will probably be buying more in the future. It is durable and a great value for the price. It is all around worth the price. I recommend it.

This Rain-x stuff works so well! I was driving in the rain and the droplets just flew off my glass. It makes it crystal clear to see through the windshield and really helps with night rain. I am definitely putting this on all of my future cars.

I used the same product for 10 years in a yellow bottle without the Cerami with no problems. Everything stated on this new bottle is a lie, Improved formula and smear free. My Tesla is mostly glass including the roof. I spent and hour yesterday applying then trying to remove the smeary mess it left on windows. This morning went to drive car and can barely see thru the windows. Really upset with this new formula and too late to get my money back from Amazon.

Clean your windows very good and the spray this on it and kinda rub it in to have it absorb into the glass really well and then micro cloth dry it well. It works best if it not already raining. I wouldn't recommend putting in on in the hot sun because it will dry and streak very fast before you have a chance to rub it in good.
