Well I washed car... Before I've used glass cleaner (ag fast glass) but didn't this time as thought I'd just reapply on top after washing car... Anyways, small blob on microfiber cloth, rub on glass in little circles... Wait a little (roughly time it takes to cover rest of screen, plus a min more) then wipe off smears with dry paper towel (as per instructions on bottle)
although for side glass I started buffing off with microfiber... Haven't seen any difference between the two sides (did drivers with paper,, passenger with micro)
So yeah.... :S I'm crap at this detailing stuff!, haha. I think I need to get someone who knows what they're doing to go round it with a full deacon, da, was/sealant whatever, show me how to do it, and give me a good starting block as it were... Easier to keep it clean from clean IMO...
