Your Güiro has been treated in the United States with tung oil to protect the wood and provide a long lifetime. Regular rubbing of the exterior surface with a soft cloth will deepen the sheen of the natural bamboo wood. This, and regular playing and handling, is all the maintenance your Güiro requires.
