How do I clean vinyl siding without a pressure washer?
Wouldn't have believed it if I hadn't seen it.  I wish I took before/after pics.

Bought:

Jomax



Clorox Outdoor



Put in a garden sprayer designed for bleach according to instructions on Jomax:


3/4 cups Jomax
2 1/4 cups bleach
13 cups water




For 75% of the siding, I applied the mixture, then rinsed after 5 minutes.  A number of sections needed a second application, and the worst section took three.

I rinsed using one of the "fireman" nozzles on my hose, just so I could get it up to the eaves:



I did try just spraying the mildew with the nozzle...worthless.  "Firemen" should sue for defamation.

Anyway, I'm thrilled.  Probably took 25% longer than last year, but I wasn't dripping wet either :)  I'll get a power sprayer for next year, but I'll definitely stick with this; it looks much better than what I get from pressure washing alone.
