Hi Everyone,
Hope you can help!
I'm quite new to window cleaning and have been cleaning the same shop window every two weeks for the last six weeks.
This morning I cleaned in the same way as usual but it has left spotting!
The glass is old and single glazed and the window frames are wood.
Can anybody suggest what I have done wrong?
I use a wfp system and the resin was replaced about 1000 litres ago.
Any advice would be appreciated
Ian
