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.
