Will pressure washing remove algae?
It can remove surface growth, but method and pressure should suit the material and repeat growth can occur.

Patio green and slippery: how should it be cleaned?
Shaded, damp paving can develop algae and organic growth. The correct cleaning approach depends on the paving material, joints and condition.
What to do next
A sensible first check
✓ Identify the paving material if possible
✓ Keep people off very slippery areas
✓ Remove loose debris before deeper cleaning
✓ Avoid maximum pressure on vulnerable surfaces and joints
When should you act?
Slippery access routes and steps should be addressed before they cause a fall.
