Has anyone ever put their pressure washer to exterior stucco? I have a
shop in my back yard that is white stucco that's turning drab (built in

Yep, yesterday. Start off slowly with an adjustable fan tip, and

handle. Start at the top and work down in about 4ft wide sections.
Give the bleach a little time to work thin rinse.
