Back in the day the guy I worked with did storefront and house awnings using a WFP/brush. For the life of me I don’t remember what chemicals he used. Some were vinyl, some were the fabric or canvas material.
I had a long time customer ask if her small canvas awnings could be cleaned, it seems to have black mildew and algae growing on it. I’m hesitant to use SH, any suggestions?
Be very careful going into awning cleaning, I used to bid a lot at the outdoor malls and the big thing is peoples expectation is that they will look like NEW…Not going to happen. Down play results…For Canvas use Winsol with any kind of brush pole combo and rinse well. I used to bid the first awning then added price per ft there after. I have done awnings for $200 that took 15 min…Winsol has a Vinyl Cleaner as well…
