3. Wooden Utensils and Cutting Boards
Wood and prolonged exposure to water don’t mix well.
Wood naturally absorbs moisture. Repeated dishwasher cycles can cause wooden spoons, cutting boards, and other utensils to swell and contract, eventually contributing to warping, splitting, or cracking.
Better Care
Wash wooden items promptly by hand with warm, soapy water. Avoid soaking them for long periods.
Dry them thoroughly with a clean towel and allow them to air-dry completely before storing.
Wooden cutting boards may also benefit from occasional conditioning with a food-safe board oil or conditioner according to the manufacturer’s recommendations.
4. Nonstick Cookware
Nonstick cookware requires gentle handling to preserve its cooking surface.
Depending on the product and manufacturer’s instructions, repeated dishwasher exposure may contribute to deterioration of the coating, particularly when combined with abrasive detergents, high heat, or contact with other utensils.
Better Care
When the manufacturer recommends hand washing, use warm water, mild dish soap, and a soft sponge.
Avoid abrasive scouring pads and metal utensils that can scratch the cooking surface.
Always check the manufacturer’s care instructions, because some modern nonstick cookware is specifically designed to be dishwasher-safe.
5. Crystal and Delicate Glassware
Fine glassware and crystal can be more vulnerable than ordinary drinking glasses.
Powerful water jets can cause delicate pieces to move or collide, while repeated exposure to dishwasher conditions can contribute to scratching, cloudiness, or surface damage in some types of glassware.
Thin stems are particularly vulnerable to breakage.
Better Care
Wash delicate glasses carefully by hand using warm water and mild dish soap.
Place a soft towel or protective mat in the sink to reduce the chance of accidental impact, and dry the glassware gently with a lint-free cloth.
Avoid gripping delicate stems too tightly while washing.
6. Copper and Brass Cookware
Copper and brass are beautiful materials, but they can react with cleaning chemicals and gradually lose their original appearance.
Dishwasher detergents and heat may contribute to tarnishing, discoloration, or deterioration of certain finishes.
Better Care
Hand wash copper and brass cookware with warm water, mild soap, and a soft cloth or sponge.
If the cookware has a special finish or lining, follow the manufacturer’s cleaning recommendations rather than relying on homemade polishing methods.
This is especially important because some copper cookware has an interior lining that requires specific care.
7. Soft Plastics and Certain Food Containers
Not all plastic containers are created equal.
Some are specifically designed to withstand dishwasher temperatures, while others can warp, discolor, or lose their shape when exposed to heat.
Thin lids and flexible seals can be particularly vulnerable.
Better Care
Look for the manufacturer’s dishwasher-safe symbol or instructions. If the container is approved for dishwasher use, placing it on the top rack is often preferable when the manufacturer recommends that placement.
If you’re unsure whether a plastic item can tolerate the heat, hand washing is the safer choice.
8. Insulated Mugs and Tumblers
Insulated travel mugs and tumblers deserve special attention because their construction is more complicated than that of an ordinary cup.
Some products contain vacuum-insulated double walls, coatings, adhesives, or specialized seals. Excessive heat or improper cleaning can damage certain components.
Better Care
Check the manufacturer’s instructions before putting an insulated mug or tumbler into the dishwasher.
When hand washing is recommended, separate removable lids, gaskets, and seals. Wash each component thoroughly and allow everything to dry completely before reassembling.
💡 The “When in Doubt” Care Protocol
Not sure whether something belongs in the dishwasher?
Use this simple checklist:
1. Check the manufacturer’s instructions.
The care label or manufacturer’s website should be your first source of information.
2. Look for a dishwasher-safe symbol.
If the item is clearly labeled dishwasher-safe, follow any additional instructions about rack placement or drying settings.
3. Consider the material.
Wood, cast iron, delicate glass, copper, and certain coated surfaces generally deserve extra caution.
4. Think about the item’s construction.
Seals, glued components, insulated walls, painted decorations, and delicate finishes can require special care.
5. When uncertain, hand wash.
A few minutes of gentle hand washing is often much cheaper than replacing an expensive kitchen tool.
What Can Usually Go in the Dishwasher?
Many everyday kitchen items are designed specifically for dishwasher cleaning, including numerous modern plates, bowls, drinking glasses, stainless-steel utensils, and dishwasher-safe containers.
The key is not to assume that every item made from the same material has identical care requirements.
Two plastic containers may look almost identical, yet one may be dishwasher-safe while the other can warp in high heat.
Final Thoughts
The dishwasher is an incredibly useful kitchen appliance, but it isn’t a universal cleaning solution.
Taking a few extra minutes to hand wash cast iron, quality knives, wooden utensils, delicate glassware, and other sensitive kitchen items can help preserve their appearance, performance, and lifespan.
When you aren’t sure, don’t rely on appearance alone. Check the manufacturer’s instructions first. A little extra care today can help keep your favorite kitchen tools working properly for years to come.
