Cedar, just a heads up. Using the power washer on siding isn't recommended as it forces water under the siding and that's not a good thing. What's popular out here in the northwest is a product called 30 Seconds. Our garden section of our grocery store sells it. I bought the smallest bottle today to give it a try. Looks like the main ingredient is bleach. On my painted wood sided shed I spray on Clorox cleaner and the mold disappears nicely. I usually spray it on the day before I know it's going to rain so the bleach doesn't just sit on the wood. Just sharing what works for me. Have done it for 3 yrs now and it's working for me. I have NOT tried it on my vinyl house siding, though.
