During washing, do not soak wood items in water. Always dry off, and from time to time rub the piece lightly with food safe oil for protection - we use organic flax seed oil mixed with beeswax. If you notice small marks appear caused from water or food, not to worry this is likely to happen. To return its original sheen, lightly sand in circular motions with a touch of oil and small piece of 600/1000 grit wet/dry sandpaper.
