To remove stains on your concrete, the first step is to mix Trisodium Phosphate (TSP) and an absorbent material like talc or baby powder to make a smooth paste.

Apply this paste to the stain. The cleaner will slowly soak into the concrete and break up the stain.

Once the paste is completely dry, scrape it off with a pallet knife and sweep it away.

Scrub the area with a nylon brush and hose off the area. If the stain is deep you may need to try 2-3 applications.
