An outdoor concrete bench adds style and decor to your garden. In addition, concrete garden benches create extra seating when entertaining guests. However, concrete benches are constantly exposed to the elements -- wind, rain and snow. For this reason, benches might become dirty or stained. You might consider replacing worn or dirty benches. But before spending money on a new bench, clean the concrete to see if you can remove the stains.

Remove cushions or pillows from the concrete bench.

Sweep the bench with a broom to remove particles, such as dirt, dust, grass and leaves.

Step 3

Fill a bucket with warm, soapy water. Use a mild detergent and avoid solvents, such as ammonia.

Dip a strong abrasive sponge or a heavy-duty wire brush in the bucket and scrub the concrete bench to lift and remove stains.


Step 6

Rinse the concrete bench with a water hose.

Step 7

Dry the bench with a cloth or towel.
