What is the best way to clean green stains off my wood siding house?

I think it is mildew or algae. I live on the Gulf Coast and it is mainly on the North side of
the house. Thanks.

    They make a cleaner you can get that can be attached to the water hose. Check at the deck store or Home Depot.

    mix bleach with water in a pump sprayer and spray it on there, let sit for a few minutes and then wash with a power washer or just a spray nozzle on a water hose if you don't have a power washer

    I use 1 part bleach to 5 parts water. Try to do it on an overcast day. It dries too fast in sun. Don't make the solution stronger, it is a waste. I live in humid (usually) Florida and have trouble with same. Oh yeah, I put a splash of very cheap laundry detergent in it to keep the solution wet longer (time is what you need).
