WTF am I doing wrong with Rain X?
Discussion
Bought a two pack set last week of demister and normal Rain X. I absolutely cannot get the demister to work without massive streaks and smears on the inside of the windscreen. It's doing fine on the drivers door window but all I've got is streaks/smear on the windscreen. Car is a 2015 Corsa so no tinting etc that I know of. I made sure to clean before hand using AutoGlym Fast Glass.
Yeah if it's on the inside there'll probably be a layer of crud from the plastics off-gassing over the years and humidity and dust bulidup. It's only a very thin film that's all what's required to stuff things up. It's also hard to remove so you'll need to clean the glass thoroughly with glass cleaner type of stuff before applying the Rain X.
Rain X is ok but not a patch on now discontinued product whose name I have forgotten. But I can't forget its packing as it looked like a pink sex toy (I'm reliably informed) . It lasted ages , unlike Rain X and at anything above about 15mph the drops just slid off the screen, at speed .
Applying rainX is a bit of an art - clean the screen then apply with a clean paper towel. You have to put enough on that it then flows and clears without running. I've never used the exterior one with much success.
I wear glasses and use foggywipes when on my motorcycle. Never had any issues with them, so I'd guess is more the glass is dry and clean with a small amount of anti fog.
When racing we often use washing up liquid, if you then warm the wiped area after it clears while youre doing it. Works equally as well as rainX IMO.

Ombrello? That stuff was brilliant but last time I checked on eBay (pre-Brexit) it was getting expensive and coming from Spain!Chris
ETA - just checked again and 12 quid for 2 ampoules on eBay. Ordered!!

I must be one of the few who thinks it works then. I've used it on a car with a weak wiper motor to help with the MoT and it really does allow water to bead off. I've used it on the outside of motorcycle helmet visor too, although it was a few years ago, I no longer use a bike in the rain.
Perhaps the recipe has changed, like so many products with marginally harmful ingredients? I found that you don't even really need the wipers in light rain at speed! My only complaint is that it doesn't seem to last very long.

Rainx works fine, I think that anti fog one is some sort of wind up experiment they've put to market though because it's only ever made windows worse for me. Once it ever reacted/I left it on too long/put too much on or something and it turned into some sort of jelly paste thing on the tinted side and back windows.
