Care and Cleaning
Once you've assembled your collection, you want to keep each piece in perfect condition. This means scrupulous cleaning on a regular basis and safe storage away from dust and strong vibrations. Be careful not to use harsh cleansers or else you may damage the finish. Do not overstimulate the spring during cleaning or your head may cease to bobble.
