It may be applied directly to rusted iron & steel tools or to rusted surfaces. The red iron oxide is converted to a black ferric phosphate, which can act as a short-term rust inhibitor. It is used cleaning masonry or bricks, pre-cast concrete and concrete surfaces.

Brick cleaners use it to remove mortar residue, lime & hard water deposits, efflorescence, acid burn stain, rust and other dirt and grime. It is a milder alternative to other acid cleaners.
