I'm going mad trying to get rid of NXT Tech Wax residue from my windscreen! Where the wiper blades change direction on the glass I get smearing, I've cleaned the glass with Mer windscreen cleaner three times, and tried water with a drop of Fairy, and it's still doing it. Each time I've cleaned the glass I've cleaned the wiper blades with AutoGlym fast glass. I'm kicking myself for not cleaning the glass after waxing and before using the wipers.
I've found some Ambersil glass cleaner in the garage, I know it's messy to use but I'm getting desperate now lol.
Can anybody suggest anything - please???
