A question for you,
I am having problems with my windscreen, when its damp or cold the windscreen when wiped with wipers clears but its like grime or something comes back up on it straight away, I have cleaned the windscreen numerous times but the problem continues until the car heats up and then goes away, it is not the windscreen fogging up, this is something else. Any ideas? Would it be a problem with wind shield itself, internal in the glass?
