F-9 works great for cleaning rust off from shingles. Mix it with water at 50/50, make sure the shingles are dry. Spray on affected areas and let sit for a few minutes (do not let dry) then spray affected areas again, let dwell for another few minutes (do not let dry) then rinse.

Hi guys, I looked at 3 mahogany decks today totaling 1700sq ft which are just gray. What would be the best way to clean the decking and railings to get rid of the gray? These decks are next to a vineyard-100 ft away. I need to use the safest chemicals possible. Any insight would be appreciated...
