Does anyone have a tried and trusted method of cleaning the inside of the windscreen glass? I have used a number of off the shelf cleaners but have still not found one that does the job effectively.
I find just about everything I have used leaves smears, which can be removed with a soft polishing cloth when the screen is completely dry . Even so once the sun shines through there is always a patch I've missed. (Hate doing the front screen, one has to be a contortionist )
RainX 2-in-1 glass cleaner + rain repellent, and before some smart guy adds it does not rain inside the screen think of condensation £2 at Asda the last few times I have popped in Arctic
