Wooden cooking items, such as spoons, rolling pins, cutting boards, and other utensils, should generally not be put into the dishwasher due to several reasons:
Water damage: Wood is a porous material, and prolonged exposure to water can cause it to swell, crack, and split. The high heat and pressure in dishwashers can accelerate this process, leading to warping and deformation of the wooden items.
Deterioration of finish: Wooden utensils often have a protective finish, such as oil or wax, to seal the wood and prevent moisture absorption. Dishwasher detergents and high temperatures can strip away this protective layer, leaving the wood susceptible to damage.
Chemical exposure: Dishwasher detergents and rinse agents may contain harsh chemicals that can be harmful to wood and may cause discoloration or degradation of the surface over time.
Cross-contamination: Wood is more porous than other materials like stainless steel or plastic, making it more likely to absorb and retain food residues and bacteria. The high temperatures in the dishwasher may not effectively remove all the food particles from the wood, potentially leading to cross-contamination with future use.
Loss of natural oils: Wood naturally contains oils that help maintain its smooth and polished surface. Dishwashing can strip away these oils, causing the wood to become dry and susceptible to splintering.
To care for wooden cooking items properly:
Hand wash: Wash wooden utensils by hand using mild soap and warm water. Avoid using harsh scrubbing pads or brushes that could damage the wood's surface.
Dry immediately: After washing, dry the wooden items with a clean towel immediately to prevent prolonged exposure to water.
Regularly oil the wood: Periodically apply food-safe mineral oil or specialized wood conditioner to keep the wood nourished, moisturized, and protected.
Avoid prolonged soaking: Never soak wooden utensils for extended periods, as this can lead to water absorption and damage.
Store properly: Store wooden utensils in a dry, well-ventilated area to avoid moisture buildup.
By following these care tips, you can prolong the life of your wooden cooking items and maintain their functionality and appearance.
