    We did ours with some bleach/water - about 10% solution. We applied it with an old rag/towel and sponge from a bucket to make sure we killed the mold and then we rinsed it off with water from the hose. To keep it from coming back try trimming up trees and shrubs to give it some more sun. If it is in a shady area it is likely a job you will have to continue to do.

    Use Wet and Forget which is a safe product for all materials.

    RENT A PRESSURE WASHER OR HIRE SOMEONE TO POWER WASH THE HOME IF THERE IS A LOT OF MOLD. THERE ARE CHEMICALS THAT CAN BE PURCHASED TO PRE-SOAK THE AREAS PRIOR TO WASHING. MAKE SURE YOU FOLLOW THE INSTRUCTIONS IF PURCHASED. HOWEVER, I HAVE FOUND THAT A MIXTURE OF 1/3 TO 1/2 CLOROX TO WATER WORKS WELL. USE A HAND PUMP GARDEN SPRAYER (1-2 GAL) AND APPLY IN SECTIONS THAT YOU CAN LET SOAK AND RINSE BEFORE DRYING. AS FOR KEEPING IT OFF YOU WILL NEED TO WASH HOME AS NEEDED OR CUT TREES FOR SUN.

    Clorox makes and Outdoor Bleach that won't damage shrubbery, flowers or grass. Add a little dishwashing liquid to the bleach/water solution to help it adhere to the siding better while it's working on the mildew, then rinse. This works about as well as more expensive siding-cleaning products you can buy. I have to clean my white siding every year because of all the trees and shrubbery we have around the house. Just something we have to deal with.

    I put bleach in a one gallon bug spray container that had a pump spray and just sprayed our light green siding and the mold dripped right off! Years of mold literally dripped off in seconds! Amazingly easy! You can dilute the bleach and or add soap but I didn't!

    I agree with all the solutions mentioned, is this area in a shady spot? If so see if t can be altered so the sun's rays can reach it. Typically mold likes dark, moist places to grow.
