According to Mr E, the outside of his windows hadn't been cleaned for about 20 years, so I was on hand to give them a bit of a wiping down.

He had the necessary cleaning fluid and some wipes for drying the windows afterwards so I was able to get stuck straight in.

I tackled a total of 6 panes in total, and whilst doing so he enquired as to whether I cleaned windows as my job which must have either been out of incredulity or hopefully a resounding endorsement of my handiwork. Hopefully the latter.
