How to Clean Badly Soiled Concrete Patios

By April Dowling

Distinguished for their decorative appeal and versatility, concrete patios are stained, engraved and stamped to provide artistic designs that complement any landscape. Although invulnerable to pests, rot and splintering, concrete patios aren't resistant to soiling from dirt, grease stains and loose debris. Heavily soiled concrete patios are eyesores, no matter how expensive or beautifully adorned they are. Properly caring for concrete patios is crucial to maintaining their appearance and preventing resurfacing. Clean a badly soiled concrete patio using simple cleaning agents.

Step 1

Sweep the concrete patio surface with a stiff broom to clean off loose debris such as twigs, leaves and trash. Remove as much debris from the patio as possible.

Step 2

Attach a regular garden hose to a spray nozzle. Spray the soiled patio surface with water, rinsing off as much dirt as possible.

Prepare a cleaning solution for badly soiled areas of the patio. Squirt 1 tbsp. of liquid dish soap into a bucket and fill the bucket with 2 gallons of fresh water.

Step 4

Scrub the stubborn dirt and grime stains off the patio using a nylon scrub brush and the soapy water. Continue scrubbing the soil until it detaches from the patio.

Step 5

Spray the patio with water to rinse off the soapy water and detached soil.

Step 6

Examine the patio for grease spills from grills or lawnmowers. If you discover dark, oily blemishes, sprinkle cat litter over them. Let the cat litter absorb the oil for 48 hours.

Sweep up the grease-soaked cat litter with the broom.

Step 8

Squirt dish soap liberally over the remaining grease stain. Wet the grease with hot water. Using the nylon brush, scour the soapy concrete until the grease stain is completely eliminated.
