California shutters are very easy to clean – much easier and quicker than drapes, blinds or shades. With any shutters you can just use a normal surface cleaner for any stubborn marks or stains. For normal periodic dusting, just use a dry or damp cleaning cloth or wipe.
With wooden shutters, you should stick to using a dry cloth, or if you do use a damp cloth try not to leave any excess moisture on the wood that could cause the wood to swell or warp.
