Softwash or power wash building?

Here is a storefront that has had old signage removed and wants the discoloration from the old signage above the awning (hope you can make out the pic…)removed.
Will probly include the metal awning
Will softwash remove this???
What would you use on the metal awning???
(also posted on wcr hopeing to get a fast reply… THANKS!)

SoftWashing will clean it. It won’t restore it so it looks like the sign was never there. You will prob see a light “ghost” image. The only way to make it look perfect is to clean it properly and then paint a large section of the wall.
