All finishes are non-toxic, organic, and food safe. For items made to be used, just wash unpainted parts with warm soapy water, or brush under a running cold tap, without immersing the whole item; rinse and towel dry (not dishwasher safe!). To rejuvenate the wood once or twice a year wipe on a generous coat of mineral, RAW linseed, tung, or walnut oil. Let soak overnight before polishing off any excess.
