Any recommendations for a good glass cleaner? I used the Rain-X spray at the weekend, but its just left a streaky mess in direct sunlight.
Have you tried soapy water? Or a detergent. It sounds like you might have an oily deposit that regular glass cleaners can't get off. Or, conversely, what car wash are you using on the outside? If it has wax in it, perhaps this is what the deposit is, and the window cleaner can't remove it.I've tried every trick in the book. NOTHING WORKS. I gave up on having an attachment to such a high standard, lol.
WOW!!! you deserve a cold one...cheers!!!Boy, did I have bad luck with Rain-X spray. Okay, it was a bottle that I'd bought several years ago, so maybe its age had something to do with it. I washed the car, then found that bottle of RainX and went to work on the windshield, inside and out. Ugh. The windshield, when the sun shined on it, looked like it was covered with plastic food wrap. I re-cleaned, and cleaned, and cleaned. My go-to for years, Sprayway glass cleaner, wouldn't touch it. I then mixed a couple drops of dishwashing liquid in a spray bottle of warm water, that helped a bit. Grabbed a bottle of 409 spray cleaner, that helped a little more. (By now, I'm probably just wearing through the Rain-X.) Finally pulled out the big guns. I put on some nitrile rubber gloves, grabbed the gallon bottle of blue windshield washer fluid (which was labeled as containing methanol) and a fresh roll of paper towels, and went to town. The RainX was still working, the blue juice beaded and ran, but after 2-3 cycles with the blue stuff, the windshield pretty much came back to normal. That Rain-X is now awaiting delivery to the household hazmat drop-off site, I never want to see that stuff again.
I went out for a few hours of sunny sky driving today and didn't see any streaking/cloudiness on the glass.
I second this. If the label says "Flammable, keep away from flame" you know it's alcohol based and will dry/ evaporate streak free.I use Invisible Glass
