One of my customers wanted her atrium windows cleaned and they’re coming out ok but clearly not like brand new or a result I feel content with. My process is to water fed pole them and I even took a little white pad and it’s not really even removing the thick layer of grime that’s built up. It’s in a wooded area so a lot of grimes been building up on them since last year. I did this job last year and I guess the result was satisfactory for her since she called me again. There’s a lot of like algae / organic stuff that’s just heavily built up on the top and im wondering maybe If downstreaming would help? lol. I’m just gonna do a regular cleaning and the way it comes out is how it comes out but my question is does anyone have any idea or experience on how to do a restoration service for this? This is more so for my own curiosity I don’t really plan on doing a restoration service. Here are some pics of where it’s super dirty and where I cleaned (you can see some black marks on them that don’t come off). Again the glass just has a lot of organic stuff on top of it.
