A local bank we have done some business with is looking to get a quote for pressure washing their building. I do a lot of house washing but, I have not done a lot of commercial pressure washing. What would be the best chemicals to use on this?
What type of surface? Organic or non-organic stains? Test a spot before you send a bid to know what you are dealing with.
They are organic stains. I will definitely test it before sending a bid. Thanks.
Test spot with house wash mix, but more than likely may have to DS straight SH w/ surfactant.
