S/V40 Glass cleaning.
How do you clean the ‘grease’ from the inside of the windscreen?
Problem specifically relates to my V40, but seems to be an issue to some extent in every car I have owned with a leather interior. I assume it is from leather conditioners - the old S40 got much worse after I treated the leather.
It’s like someone has smeared the inside of the glass with Vaseline, and the only thing you have to clean it is a Vaseline soaked rag - you can move it around, but never actually clean it off.
So far, I have tried a variety of glass cleaners, metho, carby cleaner, adhesive remover (Scotch700) - the grime just laughs at them.
I can get it so that it is fine on a dry, warm day, but a cold morning leaves a fog on the glass that the demister can’t cut through (yes, the heater works fine).
New experiment will be electronic contact cleaner, but I am losing hope...
