To remove efflorescence, light rust or general jobsite dirt, we recommend testing Sure Klean Light Duty Concrete Cleaner, our mild, non-etching cleaner for hard surfaces. It works on a variety of masonry substrates, and it removes efflorescence, light surface rust, and general jobsite dirt and soiling. 

Light Duty Concrete Cleaner is typically mixed at up to a 1-part-concentrate, 3-parts-water dilution.
