I put some Rain-x on my windshield on the outside. I noticed they sell one bottle for the outside of the window and one for the inside. I figured they just wanted to sell two bottles and it's the same stuff. It works fine on the outside. Rather than do the whole inside, I thought I'd try it first and only did 1/4 of the windshield. I guess the outside type dont work too well inside. When it's cold, the part with the Rain-x gets all fogged up, while the rest of the window dont. Worse yet, it's really hard to wipe off the fog, or whatever is the correct word for that. (It's not cold enough to be frost, but it's fogged up with moisture).
I guess I just have to remove it from that 1/4 th of the window. Anyone know what will remove it?
Thanks
