clean siding quickly, but more pressure is not always better.
Used incorrectly, high-pressure water can:
force moisture behind siding
damage paint
mark softer materials
loosen panels
damage caulking around windows and doors
For ordinary algae, allowing an appropriate cleaner to do most of the work is often safer than trying to blast the stain away.
If you do use a pressure washer, follow the siding
little help.
Use a soft-bristle brush and gently work the affected area. You usually do not need heavy pressure once the cleaner has had enough
