Dishwasher Safe Items: The Complete Guide

Illustration of dishwasher safe items including plates, mugs, utensils, and containers

Wondering if something can go in the dishwasher? You'd be surprised how many items are perfectly safe. This guide covers every category of kitchenware and household items you can confidently load into your machine.

Ceramic and Porcelain

Standard ceramic and porcelain dishes are the bread and butter of dishwasher loads. These materials are fired at extremely high temperatures during manufacturing, making them highly resistant to the heat and water pressure inside a dishwasher.

Dinner plates and side plates — all standard ceramic plates are dishwasher safe
Bowls — cereal bowls, soup bowls, and serving bowls made of ceramic or porcelain
Mugs and cups — coffee mugs, tea cups, and travel mugs (remove lids first)
Serving platters — large ceramic platters and dishes
Baking dishes — ceramic and stoneware baking dishes (like casserole dishes)

Pro Tip: If your ceramic has gold or silver trim, hand wash it instead. The metallic decoration can fade or flake off in the dishwasher over time.

Glassware

Most glass is dishwasher safe, and modern dishwashers have gentle cycles specifically designed for glassware. The key is proper placement.

Drinking glasses — tumblers, pint glasses, juice glasses
Wine glasses — place stems between the tines of the top rack for stability
Glass measuring cups — Pyrex and similar borosilicate glass is extremely durable
Glass storage containers — with lids removed and placed separately
Mason jars — jars and lids (non-rusting) are both safe
Glass baking dishes — let them cool to room temperature before loading

Caution: Hand-blown, antique, or crystal glassware should be hand washed. The high heat and detergent can cause clouding or etching on delicate glass.

Stainless Steel

Stainless steel is one of the most dishwasher-friendly materials. It resists corrosion, handles heat well, and comes out looking great.

Stainless steel pots and pans — unlike non-stick, stainless steel handles the dishwasher beautifully
Mixing bowls — stainless steel bowls are dishwasher workhorses
Utensils — stainless steel spoons, spatulas, tongs, and whisks
Water bottles — most stainless steel bottles (check manufacturer guidelines for insulated ones)
Baking sheets — stainless steel baking sheets and cooling racks

Plastic and Silicone

Most modern plastics are designed to be dishwasher safe, but placement matters. Heat rises in the dishwasher, and the bottom rack is closest to the heating element.

Food storage containers — Tupperware, takeout containers, and meal prep containers (top rack)
Plastic cutting boards — the hot water actually helps sanitize them
Plastic utensils — serving spoons, ladles, and spatulas
Silicone spatulas and spoons — silicone is heat-resistant and dishwasher safe
Silicone baking mats — roll or fold to fit on the top rack
Silicone ice cube trays — the dishwasher removes odors and stains
Baby bottles and sippy cups — disassemble completely before washing

Pro Tip: Always place plastic items on the top rack. The bottom rack is too close to the heating element and can cause warping or melting with some plastics.

Metal Utensils and Flatware

Your everyday silverware and metal cooking utensils are dishwasher safe with a few caveats.

Forks, spoons, and butter knives — load with handles down for best cleaning
Serving utensils — ladles, serving spoons, and tongs
Can openers — the removable parts of manual can openers
Stainless steel straws — place in the utensil basket
Cookie cutters — stainless steel or tin-plated cutters

Note: Don't mix sterling silver and stainless steel in the same compartment. A chemical reaction between the metals can cause permanent discoloration on the silver.

Surprising Items You Can Dishwasher

Beyond standard kitchenware, many household items are dishwasher safe. Here are some you might not have considered:

Kitchen sponges and brushes — the hot water sanitizes them (top rack)
Refrigerator shelves and bins — remove, let them come to room temperature, then wash
Vent covers and grilles — metal or plastic vent covers come out like new
Soap dishes and toothbrush holders — ceramic or plastic bathroom accessories
Pet dishes — both ceramic and stainless steel pet bowls
Light fixture covers — glass or plastic light covers (not electrical parts)
Removable stove knobs — check your stove's manual first
Plastic toys — small plastic toys without batteries or stickers
