Hi all, Ive recently started window cleaning. We moved near Melbourne 10 years ago, so most houses here are one storey (or bungalows to you). I've just done a couple of two storey houses. When I squeegee off the window it never comes off clean, there's always streaks left behind under the squeegee which is good quality and brand new. Any suggestions what I'm doing wrong please. Should I stand real close to the building or further back. The house I done yesterday I put a wetter mop onto the window and less dish cleaner in the solution and although better still had a couple of marks. Any good tutorials on YouTube or advice would be most appreciated. Thanks, Neil.
