You’ve all just summed up everything I was going to write! Greasy windshield a day or so after cleaning. I’ve changed the brand of windscreen wash I use, I’ve diluted more, I’ve diluted less and still it’s the same. Perhaps it might be down to the wiper blades?

As far as I'm aware, this thread is talking about the inside of the windscreen, not the outside.

Which would explain why changing the screen wash hasn’t done a bloody thing then! ;D

Having said that, I thought both inside and outside were a pain, at least now I know it’s just the inside. But yeah the inside is definitely a pain, I’ve also got those big ring marks and no amount of glass cleaner or microfibre cloths get rid.
