Homemade Concrete Cleaner

Things you will need to clean your concrete

1 Quart Bleach
2 Gallons warm water
2 Large pails and a scrub brush

Combine the bleach and warm water in a pail.Pour mixture onto dirty or stained concrete. Scrub the concrete with a bristle brush. For stubborn stains let it soak for 20 minutes. Then rinse the concrete with clean water. Note: If you are cleaning an area where there is grass, rinse thoroughly to dilute the bleach so it doesn't kill your grass.

This mixture as well as a commercial grade cleaner will probably only remove so much of the stain. Typically over time the stain will just fade away.
