ANY ADVICE ON AN EFFECTIVE AND EFFICIENT FOR CLEANING CEDAR SHAKES? I SAW PREVIOUS POSTS MENTION COPPER SULFATE AND SODIUM HYDROXIDE FOR CLEANING. I'VE ALSO SEEN "APPLE SAUCE" IN A POST. PLEASE ADVISE AS THE SHAKES ARE CLOSE TO 30 YEARS OLD WITH LITTLE ALGAE AND MOSTLY DARK GREYING.:confused: Roof Cleaning Cedar Shake IL

Cedar shakes are much more challenging and expensive. For all types of wood the best chemicals to use are sodium percarbonate with a little sodium hydroxide, pressure wash, and neutralize/brighten with oxalic acid.

After you let the shakes dry seal with a good quality oil-based stain. I like ReadySeal, Wolmans, and WoodTux. WoodTux can be applied to damp wood, but the only thing I don't like about it is the choice of colors, which is basically red or redder.

Hey Chris, I'll give you a ring tonight.
