Revive the patio
A layer of unsightly algae, moss and mud can build up on patio slabs over winter, making them not only look grubby, but dangerously slippery too. The quickest way to remove the dirt is by using a pressure washer. Work methodically in a side to side motion, avoiding using too much pressure on any cemented joints to prevent them from being damaged.
