Well I'll agree to disagree on that one. I've been running Rain-X pretty much since it came out way way back before they even made Rain-X washer fluid. I have never had a single issue with a washer fluid pump from Rain-X. Somebody would have to be literally holding a razor blade vertical to scratch a glass especially on newer vehicles with the more resistant windshield. Holding the blade out about a 10 to 15° angle and scraping the glass like you're supposed to yields absolutely perfect results and zero scratching. Again with the Rain-X there is definitely no buildup on the windshield whatsoever as a matter of fact if you apply Rain-X and don't use Rain-X windshield washer fluid regular washer fluid will completely remove rain-X in about 5 to 6 months use if you supplement it with washer fluid you'll get well over a year before you need to reapply the windshield treatment. Same goes for aquapelle treatment. Buffing in a good wax works also personally I don't find it works as well as the windshield treatments. And yes ceramic coating does work also but usually way more expensive and will still need to be reapplied down the road adding to that expense again versus a $6 bottle of Rain-X windshield treatment that lasts about 15 applications.I do mobile detailing and the one thing I come across is people who used razor blades on their windshields and they are all scratched ... rain x causes build up especially with road grime over time and that is a fact ...
Rain x in the pump is the worst thing to do, just like @GTyankee said, it plugs up the pumps and the lines ...
But hey what do I know lol ...
Simple, best thing for windows especially the windshield is a good ceramic coating ...
It never fails that the guys that are dead set against Rain-X and Rain-X washer fluid are almost always car detailer guys that are promoting ceramic coatings. It's funny 10 years ago before ceramic coatings took off Rain-X and aquapelle were heavily promoted by detail guys especially aquafel as it was a tad bit more expensive so it could be sold at a higher premium.
