hey guys I could do with a little advice on how to do the inside window of a kebab shop. I usually only work WFP so only have the odd bits of trad gear for the occasional job. This kebab shop has one large window right next to all their cooking whatnots and the window, at the top, looks like it has drips through condensation. Each time I've cleaned it I've used increasing amounts of soap and the last time I even tried doing it by hand with a washing up scourer (one of the green non abrasive things). Nothing is really sorting it out. I'd half a mind to find a reason to not do this place! But professional pride won't let me and I'd rather find out how to do it properly. So any ideas please fellas?
