Aye, I know it's daft but I've recently had a new windscreen fitted and I can't get the inside clean.
I've tried household glass/window cleaner, car screen wipes, a microfiber gadget on a stick that makes good contact with the glass but "no".
The inside still seems to have some kind of smearing on it.
I've sprayed, wiped, rubbed and polished and I certainly know how to clean stuff cos I've been in the army y'know! TWICE !!!
Does Autoglass use some kind of 2nd rate "oily" glass that can't be cleaned?
I've used Rain-X, Astonish and Good Year Anti Smear "ha!" Screen wipes.
All to no avail.
