Did a search and it seems like most always say WFP. I have not purchased one so will do it trad method.
The homeowner has been informed that it will not be spotless btw just trying to do the absolute best job I can. I have heard some talk a bout a no squeegee/ no rinse solution on other threads but have not found a recipe for it/.
I have cleaned solarium’s with glass ceilings traditionally and got great result. Just remember to use really clean water on the final pass. I did use the Moerman Accelorator for most of the roof. I had to use a 4 step method to get them clean.
my 4 step process was to use a webster(tool for getting spiderwebs off) which you can buy anywhere. This helped get all the major debris off including pollen. Then I mopped it with my 14in sleeve. Then I used my steel wool on a wall sander (attaches to my 12’ ettore pole that I use). Finally I use my Moerman accelorator and Fliq pad to do the final clean. Everything came off with this method. At first I tried straight puls but it left streaks due to the windows being in direct sun and drying my solution. The Accelorator made it easy to get into all the corners and minimize detailing.
Those black spots on the after picture is not dirt or stains btw it’s lettering from some type of insulation/ ceiling the homeowner added to the sunroom, it turned out almost spotless.
The homeowner was pleased and asked for my cards to give to her friends and neighbors.
I definitely need to get a WFP though, I had to soap, scrub and rinse 3 times to get it right. Got a really good shoulder and arm workout in lol
