Poplar wood is a non-toxic and food-safe material that imparts no taste or odor of its own, making it ideal for contact with food. To guarantee the longevity of this soft wood, the wooden bowl should be protected from direct sunlight, heat sources, and extreme temperature and weather fluctuations, as these can dry out or discolor the wood. Moisture should also be avoided: the bowl should not be left standing in water or cleaned in a dishwasher, but rather dried in a well-ventilated place after wiping with a damp cloth.
