How to remove green mold and/or stains along vinyl siding of our house

Well, we did bad!!!! Having scrubs like hemlocks, and other flowering (forsythea) evergreen-like lower plans on the north face of our home has left green stains on siding and window shutters that do not rub off. ANY ADVICE ON HOW TO REMOVE/RESTORE? THANKS

I have heard that it works to use a soft-bristle brush to scrub on a solution of one part vinegar and two parts water. Also, I came across this formula from the Vinyl Siding Institute, trade group for the siding industry:
1/3 cup (2 2/3 ounces) powdered laundry detergent (e.g., Tide®, Fab®, or equivalent), 2/3 cup (5 1/3 ounces) powdered household cleaner (e.g., Spic & Span®, Soilax®, or equivalent), 1 quart ...»
(32 fluid ounces) liquid laundry bleach, and 1 gallon (128 fluid ounces) of water.

Thank you, Steve G, for your reply and solution! I will try this formula and get back with results and comments. BTW - nice photo!

Home Depot & Lowes both carry a homeowner friendly cleaner that screws on the end of a garden hose....Jomax makes one of them...you will find them in the paint departments at both stores. Work well. You can also wash most off with a low pressure pressure washer.

If left to grow, mildew can impregnate vinyl. Chlorine solution will kill it but it will take scrubbing to remove the stain. Ofcourse, rinse the chemical off thoroughly.

Kafko's Oil Eater. I've used the product about 20 years, on every possible cleaning dilemma from greasy shop clothes and engine parts to dishes, floors, tile, tools, driveways and even toys. Highly recommended; now available at Amazon in spray bottle, gallon or case (previously available only through manufacturer, in case quantities).

Power wash with clorox bleach and water. That's all we use down south and believe me we have lots of rain and humidity. Give a good rinse after the mixture has done its job. LIke new.

Try concrobium mold control to clean up mold. $28. a gal at Home Depot or Loews. It really works and does not smell. No fumes

Success! with the use of bristle brushes, power wash of clorox + water, and lots of rinsing. We'll see what next year shows. For now we have also removed high pollen-like shrubs, and keep pachysandra only.

Be careful about power washing as it can blow out your grout and let water into the inside wall. There is a product new to me called "spray it and forget it". It advertises itself as being "safe" for every living thing! We have a bottle to spray on our deck...just waiting for the weather to cool down a bit!

BioSafe Systems makes a product called Green-Clean that is basically very strong hydrogen peroxide that dissolves the cell walls of algae, moss, mildew, & mold on contact and is safe for all plants. Google GreenClean to find a local supplier.
