Wood Wash? With Latex & Oil Based Stain.. Question

Guy’s I have client who needs some wood washed, I say washed because they only want the dirt and dust removed from the coated surface…

I don’t do wood, But I figured they only want the dust and grime washed off… One section has a latex finished and a other section (pergola) has a oil based stain…


My question is, do I need to dry the wood after the wash? The finish is glossy and it might leave water spots behind?.. Also, is there a detergent I can use to loosen the grime?. Keep in mind we are not removing the finish just washing… Thanks in advance guys


Throw some soap on it, let it dwell a few minutes and rinse with medium pressure

No sh just soap?

How did it turn out? Did you use sh? If so how much?
