Once your walls are painted they’ll look after themselves now, right? Unfortunately, not. Walls
need cleaning too. Paint can easily come off though, so don’t use loads of water and only use
gentle cleaners. Sometimes you can get away with simply wiping the walls with a damp cloth.
Exterior paintwork can be hosed down, but any timber needs regular repainting due to rain
and sun exposure. If you live near the ocean (lucky!), you’ll have to wash external paintwork
to remove salt buildup (a small price to pay).
