It's important to season your bowl before using it. Using a clean cloth, thoroughly coat the wood with the provided mineral oil and continue to season it every so often as needed. If it appears dull or feels dry to the touch, it needs seasoning. Use warm water and mild detergent to wash the surface and never put it in the dishwasher or let it soak (this prevents cracking and warping). Also, keep your bowl out of the microwave.
