For a powerwasher why rent at 50 a day, buy an electric, you will find
alot of uses, mold comes back. Karcher is a good brand for around 200.
To bleach 30 ft up , hire someone bleach is slippery , get it on the
ladder and fall. Or use a garden sprayer. Shock is overkill with a
powerwasher, and to hard for siding or plants
