Any good wood cleaner, with any tool you'd use to clean any other type of blinds. Actually, wear a pair of cloth gloves, over good rubber gloves to protect your hands, and your fingers will get between the slats easily and shorten the time it takes. Don't soak the wood, just clean lightly with one hand & rinse lightly with the other, if rinsing is needed. Voilá!
