No, you should not put wooden spoons in the dishwasher. The high heat, harsh detergents, and prolonged moisture cause the wood to crack, warp, and splinter, ruining your spoons and potentially leaving splinters in food.
Dishwashers ruin wooden spoons by exposing them to heat, moisture, and detergents that strip natural oils and cause cracking. Hand washing with mild soap and immediate drying keeps them lasting for years.
- Heat Damage: Dishwasher drying cycles (140-160°F) cause wood fibers to expand and contract, leading to cracks.
- Moisture Absorption: Prolonged soaking in the dishwasher makes wood swell and warp, weakening the handle.
- Detergent Stripping: Harsh dishwasher detergents strip the natural oils in wood, leaving it dry and prone to splintering.
- Hand Wash is Best: Wash wooden spoons by hand with mild dish soap and warm water, then dry immediately with a towel.
Why Dishwashers Damage Wooden Spoons
Dishwashers are designed for glass, ceramic, and metal — not porous wood. The combination of high heat (often 140-160°F during the drying cycle), aggressive detergents, and long soak times creates a perfect storm for wood degradation.
Wood is hygroscopic, meaning it absorbs and releases moisture. In a dishwasher, it absorbs water and swells. When it dries rapidly in the heat, it shrinks and cracks. This repeated stress eventually splits the spoon or makes the surface rough and splintery.
Additionally, dishwasher detergents contain bleach and enzymes that strip the natural oils from wood. Once those oils are gone, the wood becomes dry, brittle, and more likely to absorb bacteria — defeating the purpose of cleaning.
When It Might Be Okay to Use the Dishwasher
Some wooden spoons are marketed as dishwasher safe, but this is often misleading. If the spoon is made from a dense hardwood like maple or teak and has a sealed finish (e.g., polyurethane or melamine), it may survive occasional dishwasher runs. However, even these will degrade over time.
If you must put a wooden spoon in the dishwasher:
- Place it on the top rack, away from the heating element.
- Skip the heated dry cycle — open the door and let it air dry partially.
- Remove it immediately after the wash cycle ends — don’t let it sit in steam.
- Check for cracks or splinters after each wash; discard if damaged.
Even with these precautions, expect the spoon’s lifespan to be cut by more than half.
How to Properly Clean and Maintain Wooden Spoons
Hand washing is the only safe method. Follow these steps:
- Rinse the spoon under warm running water immediately after use to remove food residue.
- Apply a few drops of mild dish soap to a soft sponge and scrub gently. Avoid abrasive scrubbers that scratch the wood.
- Rinse thoroughly with warm water until all soap is gone.
- Dry with a clean dish towel immediately. Do not let it air dry on a rack — standing water causes warping.
- Once a month, rub the spoon with food-grade mineral oil or beeswax to replenish natural oils. Let it soak in overnight, then wipe off excess.
Never soak wooden spoons in water or leave them in the sink. For stubborn stains, rub with a cut lemon or a paste of baking soda and water, then rinse and dry.
Signs Your Wooden Spoon Needs Replacing
Even with perfect care, wooden spoons wear out. Replace yours if you notice:
- Cracks or splits — these can trap bacteria and food particles.
- Rough or splintery surface — especially on the cooking edge, which can shed splinters into food.
- Dark, soft spots — a sign of water damage or mold growth.
- Warped shape — a bent handle or bowl means the wood has distorted and won’t stir evenly.
- Unpleasant odor — a musty or sour smell indicates deep-set bacteria or mold.
High-quality wooden spoons can last 5-10 years with hand washing and occasional oiling. Dishwasher use reduces that to 6-12 months.
Choosing the Best Wooden Spoons for Longevity
Not all wooden spoons are created equal. For the longest life, choose:
- Hardwoods like maple, beech, olive, or cherry. Avoid softwoods like pine or bamboo (bamboo is grass, not wood, but also prone to splitting).
- Single-piece construction — no glued joints that can separate in moisture.
- Unfinished or oiled finish — avoid painted or varnished spoons that can peel into food. Oiled wood is self-healing and food-safe.
- Thick, sturdy handles — thin handles crack more easily.
Stores like William Sonoma, Sur La Table, and even IKEA sell reliable options. Look for spoons labeled as ‘hardwood’ and ‘hand wash recommended.’
Pro Tips
- Rub a raw walnut half over the spoon to remove garlic or onion odors — the natural oils neutralize smells.
- Store wooden spoons in a utensil crock with the cooking end up to allow air circulation and prevent moisture buildup.
- If a spoon becomes fuzzy after washing, sand it lightly with 220-grit sandpaper and re-oil to smooth the surface.
- Never put wooden spoons in the microwave or oven, even for a few seconds — the heat causes sudden expansion and cracking.
Common Mistakes to Avoid
- Leaving wooden spoons to soak in the sink overnight — this hydrates the wood fibers and causes warping and bacteria growth.
- Using olive oil or vegetable oil to condition wooden spoons — these oils can go rancid and develop an unpleasant smell.
- Putting a cracked wooden spoon in the dishwasher thinking it will kill bacteria — cracks actually harbor more bacteria after washing.
- Scrubbing wooden spoons with steel wool or abrasive pads — this scratches the surface, making it rough and more absorbent.
FAQ
Can I put bamboo spoons in the dishwasher?
Bamboo is slightly more resistant than hardwood but still not dishwasher safe. The heat and moisture cause bamboo to splinter and delaminate. Hand wash bamboo spoons just like wooden ones.
How do I sanitize a wooden spoon without a dishwasher?
Boil water, remove from heat, and submerge the spoon for 10 seconds (no longer — boiling can crack it). Alternatively, wipe with white vinegar or a 3% hydrogen peroxide solution, then rinse and dry.
What’s the best oil for wooden spoons?
Food-grade mineral oil is the safest and most common. It’s odorless, tasteless, and won’t go rancid. Beeswax or a beeswax-mineral oil blend is also excellent for a longer-lasting finish.
Can I repair a cracked wooden spoon?
Small surface cracks can be sanded and oiled, but deep cracks or splits cannot be safely repaired. Discard the spoon to prevent bacteria trapping and splinter risk.
The Bottom Line
Wooden spoons are kitchen workhorses, but they need gentle care. Dishwasher convenience isn’t worth the shortened lifespan and potential food safety risks. A quick hand wash and dry takes 30 seconds and keeps your spoons smooth, sturdy, and splinter-free for years. Treat them well, and they’ll treat your food well.
