The Complete Guide to Concrete Cleaning

Concrete is porous, which means stains and organic growth can penetrate below the surface if left untreated for too long.

Oil and rust stains require targeted pre-treatment before pressure washing to break down the stain at a molecular level.

Algae and mildew commonly appear in shaded, damp areas — left untreated, they can make concrete slippery and hazardous.

Sealing concrete after cleaning helps protect it from future staining and extends the time between deep cleanings.
