Can You Put Wood Composite Bowls in the Dishwasher?

Some wood composite bowls can go in the dishwasher and some cannot, so the only reliable answer is the one printed by the company that made yours. Maple Origins bowls, plates, trays and serving utensils are top-shelf dishwasher safe, with any regular dishwasher detergent. A solid carved wooden bowl is a different material and usually should be washed by hand.

We make every piece in Southington, Connecticut, from a wood plastic composite (WPC): recycled maple wood combined with plastic and molded into shape. That mix is why our care advice sits halfway between a wooden bowl and a plastic one.

Can wood go in the dishwasher?

Solid wood generally should not go in the dishwasher. A long cycle soaks the wood in hot water, the detergent strips its oil finish, and the heated dry pulls the moisture back out faster than the grain can handle. After a few rounds you tend to see a fuzzy, raised grain, pale dry patches, and in the worst cases a crack or a warp.

That is the reason most woodturners and wooden bowl makers ask you to hand-wash. It is also why the question gets asked so often: the same kitchen holds wooden spoons, a bamboo board and a bowl that only looks like wood, and each one has different rules.

Why can't you put wood in the dishwasher, but you can put some composites in?

The plastic is the difference. In a wood plastic composite, the wood is held inside a plastic binder rather than left as open grain. The plastic keeps water from soaking deep into the wood fibers and gives the piece its shape, so it behaves much more like a sturdy plastic dish in the sink.

It does not make every composite the same, though. "Wood composite" covers several different products:

• Wood plastic composite (WPC), wood fiber or sawdust bound in plastic, the material Maple Origins uses.
• Bamboo or plant fiber bound with a resin, often sold as "bamboo dinnerware". The resin varies by maker.
• Laminated or glued wood, layers or strips of real wood joined with glue and finished with oil or lacquer. These are much closer to a wooden bowl and are usually hand-wash only.

Because the binders, glues and finishes differ, two bowls that look alike on a shelf can need opposite care. If yours has a care card or a stamp underneath, follow it.

Are Maple Origins bowls dishwasher safe?

Yes. All Maple Origins products are top-shelf dishwasher safe, and any regularly available dishwasher detergent can be used. That covers the Cereal Bowl, Snack Bowl, Serving Bowl, Salad Bowl, Plate, Party Tray and the Serving Fork and Spoon.

If you would rather wash by hand, that works too. Hot or warm water is what we recommend for hand washing, with your usual dish soap and a soft sponge.

Our colors are molded into the material itself rather than painted or sprayed on, so washing does not wear a coating away. Over time the pieces may darken a little with use. That is normal for the material and does not mean a bowl is unsafe to use.

Why the top rack?

The top shelf is the gentler part of the machine. In most dishwashers the heating element sits at the bottom, and the lower rack is where the hottest water and strongest spray land. Keeping composite pieces up top gives them the same treatment you would give plastic containers and lids.

A few loading habits help:

• Set bowls upside down and at a slight angle so water drains off the base instead of pooling.
• Give each piece its own slot. Bowls nested inside each other trap food and do not get clean.
• Larger pieces like the 12-inch Salad Bowl or the Party Tray may not fit on every top rack. When they do not, wash them by hand rather than moving them to the bottom.
• Keep sharp knives and metal skewers away from the bowls in the basket, since sharp metal can scratch them, the same as any wooden piece.

What happens if you put a wooden bowl in the dishwasher by mistake?

One accidental cycle does not always ruin a solid wooden bowl, but check it once it is cool and dry. Signs of damage include a rough or fuzzy surface, pale and chalky patches where the finish washed out, a hairline crack, or a bowl that no longer sits flat.

For a solid wooden bowl that only looks dry and dull, the usual fix is to let it dry fully at room temperature, then rub in a food-safe bowl oil or board conditioner. A deep crack or a warp is usually permanent, and a cracked bowl is best retired from serving wet foods.

For a composite piece that is not labeled dishwasher safe, the same check applies. Look for warping, a cloudy surface or a coating that has started to peel, and stop machine washing it.

How do I care for a wood composite bowl day to day?

Composite bowls need very little. These are the habits that keep ours looking good for years:

• Wash it soon after use, especially after tomato sauce or other strongly colored foods. Some sauces, like tomato, can stain.
• Skip metal scrubbers. Stainless steel and copper scrub pads will scratch our products. A soft sponge or a nylon brush is enough.
• Use a gentle paste for stains. For stubborn marks, scrub by hand with dish soap mixed with kosher salt or baking soda, plus a splash of white vinegar. Our care guide has the details.
• Keep it out of the microwave. Maple Origins pieces contain real maple wood, so we do not recommend microwave cooking in them. Treat them like any wooden bowl there.
• Serve cold or warm foods. Maple Origins pieces are made for both, so let a hot dish cool for a few minutes before serving it in one.

How can I tell if my bowl is dishwasher safe if there is no label?

Start with the maker. Look for a stamp or symbol on the underside, a care card in the box, or the product page where you bought it. Many dishwashers and dish brands use a symbol of a plate or glass under water droplets for "dishwasher safe".

If you cannot find anything, treat it as hand-wash only. A bowl that turns out to be dishwasher safe loses nothing by being washed in the sink, while a bowl that was never meant for the machine can be ruined in one cycle.

For Maple Origins pieces, the answer stays the same for every product and every one of our 17 colors: top shelf, any regular detergent, or a warm hand wash.

Frequently asked questions

Can wooden bowls go in the microwave?

Solid wooden bowls generally should not, and we do not recommend microwave cooking in Maple Origins products either, because they contain real maple wood. Heat food in a microwave-safe dish, then serve it in your bowl.

What is the best way to clean wooden utensils?

Solid wooden spoons and spatulas are best washed by hand in warm soapy water and dried right away. Our Serving Fork and Spoon are made from the same composite as our bowls, so they are top-shelf dishwasher safe.

Will the dishwasher fade the color?

Our colors are molded in during production, not painted or sprayed on, so they will not flake, peel or smudge. Pieces may darken a little with use over time, which does not affect their safety.

Can I use any dishwasher detergent?

Yes. Any regularly available dishwasher detergent can be used on Maple Origins products.

The short version

Check the maker's label first, and hand-wash anything that does not have one. Solid wooden bowls belong in the sink. Maple Origins composite pieces can ride on the top rack with everyday detergent, which makes them an easy choice for a family that runs the dishwasher every night.
