Wooden bowls achieve a beautiful deep luster and a patina that is only made with years of regular use and proper care. The first small nicks and scratches you put on your wooden bowl are just the first in a thousand which will give your bowl an added character that you will cherish for many years to come.
Wooden bowls can be washed using hot water and dish soap, just as you would pots and pans, but never placed in a dishwasher. My bowls are not sealed or lacquered so that you can create the patina of use that is most desirable (Like a favorite pair of shoes that fit you just right).
Here is the old adage for polishing wooden bowls; every day for a month, every week for a year, then every month thereafter.
