Wash with soapy water and towel dry. Do not submerge in water. Avoid the dishwasher, as the intense heat can dry out your piece. Once a month or so, apply a little mineral oil using a soft cloth.

Do not use cooking oils such as olive or vegetable oil. If your piece starts to feel rough or feathery, use a fine-grit sandpaper to smooth it. You can also sand out any stains or burn marks.
