I took on a one off clean last week where the chap had serious grey marks on the UPVC. They scrubbed off with a damp cloth but the brush did nothing for them. They were green in areas which came off easily as usual but they clearly hadn't been cleaned in 10 years+. I've been noticing the grey marks in the corner of windows since but never really though about it before. To cut a long story short the guy was expecting sparkling white frames which I assume would have needed UPVC polish. To scrub them to the standard he expected would have taken all day. Is there anything that can be done to tackle this or am I right in thinking he was looking for a UPVC clean and not a normal window clean?
