To properly care for and maintain wooden kitchen utensils, avoid soaking them in water, as it can cause warping. Hand wash with mild soap, rinse, and dry immediately. Periodically rub with mineral oil to prevent drying and cracking. Store them in a dry place, and never put them in the dishwasher to maintain their longevity.

The frequency of replacing kitchen utensils depends on their quality and usage. High-quality utensils can last for years with proper care. However, low-quality or heavily used utensils may need replacement sooner due to wear and tear. Regularly inspect them for signs of damage or wear, and replace as needed to maintain food safety and functionality.
