Rain-X5080217 X-treme Clean Glass Cleaner - 12 fl oz.

This product is amazing! It is the ONLY product that I have tried that actually works! There was decades of soap scum on the shower surrounds in a house that my husband and I just purchased. It took a little elbow grease to get it clean BUT it did help me remove all of the built-up soap scum. I even tried it on the outside of my exterior windows because of the dried on rain residue that hadn't been cleaned off for many years. To my delight it worked on that too! So pleased with this product and have recommended to other family members!

Used this product on the inside of windshield that seems to always be hazy… worked awesome and would purchase again!

It did take off the water spots off the windshield but after a few times. You really have to rub it in real good and use those arm muscles 😄

Not what I expected but it works great! This is a fine-cut polish, not a solvent type, wipe-off cleaner. To be effective, it does take some effort, elbow grease. Or you can use a buffing wheel. We had a film residue on the windshield that did not come off with Windex, vinegar, isopropyl alcohol, ammonia, Goof Off (All applied separately. Do not mix any of these!) After these attempts, the windshield looked clean, and yet when spraying water on it, the residue would show up. I did a test area with Rain X Xtreme Cleaner and saw that it did indeed take down the residue. I hand applied to the rest of the windshield working a circular pattern. It took about 15 minutes to do the entire windshield, although had to revisit a few areas after the spray test.I then tried it on the headlight covers and this is where the magic happens. It buffed out the fogged plastic back to a clear finish. This makes the car look years younger. I am pleased with this product.

Don’t think much of the product unless something changes on our tripI would recommend not buying it to somebody elseUnfortunately, I bought a two pack and one has been openDon’t feel like I can return it

I have to admit it when a product is this good. I had some kind of residue that was ONLY visible on my windshield when it got wet. Nobody knew what it was. Dealership couldn't figure out what it was or why it only showed up when wet but when dry, the windshield looked pristine new.. All suggested windshield replacement on a factory new car!!. First I tried Isopropyl = nothing, Acetone = nothing, Barkeepers Friend with 0000 steel wool = nothing!! Then I tried this product with some microfiber rags and... gone. All of it, gone. Super clear windshield, best ever, even with rains after using it. What can I say, it works but... with one caveat = you have to apply it properly. The instructions are very general and at first it didn't work. So, I took some time to think about it and did it one more time but this time, I used a different application technique and WOW!! super amazing results. The windshield is super clear now. I never thought it would look this clean and clear ever. No more blinding windshield glare when driving in the rain at night in fact, no more blinding visibility when raining at all after cleaning my windshield with this product. I'm glad I didn't give up the first time I used it and saw zero results. I just wished Rain-x had better instructions or a video on how best to use this product rather than letting the customer figure it out through trial and error.

This is surprisingly good stuff. I just bought a used BMW X5 that really induced glare a ton when I would turn the wipers on at night during a rain event. It was like the water was sticking to the glass and not allowing the presumably new wipers to do their job. It was rather annoying and dangerous.Long story short, after working one section of the windshield at a time using some good old fashioned elbow grease the residue, embedded sap, or whatever the heck was causing the dangerous glare was gone! There were a couple spots that required 2nd spot applications, but wasn't a big deal.I used a pretty wet microfiber cloth to wipe the various area clean, washed it off, then wiped again till the product was gone. This gave a great opportunity to see where the residue still was. The water did not bead so it was one uniform light film of water...if I saw shapes or the water was uneven then I knew that spot needed a little more help.Once the windshield was sufficiently clean, I following it up with the Rain-X Glass Treatment in the trigger bottle applying 2 coats with clean folder paper towel. The results after getting finished up were great! Naturally, this is not going to polish scratches or little chips out of a windshield, but certainly did make the windshield/wipers function like new again.There are some other bad reviews on here, but really think they must have had very different circumstances, didn't put the work in (no, this is not just a wipe on and wipe off miracle product), or had unrealistic expectations. It does work as advertised! Just don't be afraid to wear your arm out a little or take some breaks. If you do this right it's not something that will have to be repeated frequently.Just FYI I have not attempted to use this product on any clear plastic yet, but if I do I'll report back!

I bought this product to removed some dried car wash soap scum and water spots from the front and rear windshields of my car. I followed the instructions to the T. (I hand wash and wax my car frequently and the instructions are similar; thus, its not like I misunderstood something or didn't use circular, overlapping motions.) After the 1st application, there was still soap scum on the rear windshield and water spots on both. Thus, I repeated everything again. The product still didn't work.Thus, in my opinion, just save your $ until the next car wash and hope that does the trick.
