Greetings, I am new to window cleaning and pressure washing so forgive my ignorance.
I went to pressure wash this back patio and it has some stains from something some type of oil and heavy dirt residue that can’t be picked up with regular soap and the disc.
Does anyone have any recommendations for products or like a ‘go to’ item that is always used when doing concrete? I’d like to not have this issue arise when at customers homes.
I like the F9 Double Eagle for removing oil and de-greasing. You can downstream it or use pump sprayer for stronger mix ratios. For rust stains I like the powder ox-brite oxylic acid… Pressuretek has some good powder chems that work good.
