How do I get mold off of my vinyl siding? I tried power washing it, but it was not effective.?

I use a Gilmour hose end sprayer and bleach. The Gilmour costs a little more but worth it.How do I get mold off of my vinyl siding? I tried power washing it, but it was not effective.?
A mixture of water and bleach and a lot of rubbing. You don't want to put a lot of bleach in the water as it could damage your siding. Maybe a half cup or so of bleach to a gallon.
