i have an account with brick pavers with a very heavy black buildup. appreciate any suggestions on a cleaner

One restore should work. Not sure what the stain is. Do you have pics?

The pressure washing forum could help also. Another Port St Lucie window cleaner comes to the forum. Welcome.

my account is a restaurant and its a slick shiny coating. heavy grease dirt buildup

A picture would help
