Used a mixture of vinegar and sod a, mixed a bit at a time and a scrub brush on my vinyl siding...had to rinse it 3x but it worked. It took a lot of elbow grease though FYI. The next time I used bleach in my power washer. Carefully and on medium setting to not break the old siding.

I've used vinegar and water for so many different things. Hope it helps!

70% water, 30% white vinegar makes a great all-purpose vinyl siding cleaner that removes light mold and mildew stains. For a stronger solution, mix together one-third cup powdered laundry detergent, two-thirds cup powdered household cleaner, one quart liquid laundry bleach and one gallon of water.
