Which is the BEST windscreen cleaner additive that you all recommend?
I have used many, but have been unable to find one that actually removes road grease film/ spray, when its raining hard as it often does it is horrible to see through!
They all seem to leave a smear, then when the wipers are back on they are creating a greasey film all over the glass, even the Bmw windscreen additive is no better!
Is there a product that actually cleans and prevents this mess?
