Question Removing RainX from glass?

I work at a dealership and we have a customer that requested a full detail for their outback. Cleaned up just fine but we noticed that there is a streaking film that we can't seem to get off the rear window, inside. We asked the customer if he had aftermarket tint or something and apparently he applied RainX on the inside of the window. Why? No clue

Problem is, we can't seem to get rid of it. We've tried 3 types of window cleaner, degreaser and even tried a bit of brake cleaner. No luck

Anyone got any suggestions?

I heard 50/50 water & vinegar works well.

Because the Rain-X is supposed to reduce/eliminate window fogging, that's why.

Use ammonia / windex (which contains ammonia ) to remove the Rain-X.

It's not that hard to figure out.

glass is not like paint and can take more abrasive. Try Brillo (wet), or clay bar or of it s that high and if you know how, use a flat , wet, razor blade. If it s a hard water stain, vinegar , as someone stated. Let it sit awhile too.

Glass is an immensely hard surface, like people otherwise have said, and can take a beating.

I've spent years trying to figure it out on various vehicles, and no matter what chemical you throw at it, youre going to have to go at it with brute force.

Razor blades, paint thinners, and Scotchbrite pads.. of course, approach with caution. Keep the surface wet, and never let it dry. This allows for maximum penetration possible.

I misapplied Rain-X once and was going nuts trying to figure out how to remove it. It finally faded out but before it did I read that BON AMI worked well to get it off (mild abrasive). I didn't actually use it, so can't personally vouch for it.

****Edited to switch to the right product and hopefully prevent someone from scratching their glass. Got the products confused and T-37 listed the correct one.****

As long as you don't mind scratching the heck out of your glass, then sure, that would work.

Ajax is abrasive. It contains grit to help remove stains from sinks, steel pans, etc.
Put some between your fingers and move it around. Do you want that on your glass?

I've heard that a product called Bon Ami works well. There are 2 versions of it, one specifically says not to use on glass, but the other is supposedly safe and says it can be used on glass on the container. I've been meaning to try it myself, as my windshield has some type of persistent residue that causes the wipers to smear in the rain.

Give it a try and then come back and tell us how bad your window came out.

Seriously I will try it though. My windshield it chipped and fairly pitted, so worst case scenario it'll light a fire under my ass to finally replace it.

^^ LOL.
Honestly don't think it lasts very long, I'd just wait for proper use and washes to wear it down. Anything else may ruin tint or surrounding rubber/plastic.

I need to give it a try.
I notice with rain-x the wipers would form some kind of weird pattern on the windshield when it gets wet.
