None applicable for us since we are a cleaning company and cant comment on cleaning chemicals or products.
The only thing we add.
move patio furniture around to stop dark areas where the plant pots stood.
Good drainage is the key.
Don't put gravel beds by the patio doors this is a nightmare for cleaning since any bricks get kicks up and might smash your patio doors this including if you power wash or just use your hose pipe to clean it.
if you have trees Please pic up leaves as they spread Lichen and algae and makes the area slippery and very dangerous.
