Can I Put Stainless Steel in the Dishwasher?
Something else…
What else can go in the dishwasher?
YES, WITH LIMITS
Safe only under specific conditions. The conditions are the answer.
Yes, most plain stainless steel bowls, flatware, measuring tools and dishwasher-safe cookware can go in the dishwasher. Check the item’s care guide first because knives, insulated pieces and hollow handles may need hand washing. Rinse off salty or acidic residue if the load will sit, and keep stainless steel from touching sterling silver or silver plate.

The conditions
Fine to do
- The item is labeled dishwasher-safe or its manufacturer permits machine washing.
- Plain stainless steel bowls, flatware and measuring tools are generally suitable when their care instructions allow it.
- Salty or acidic food residue is rinsed off if the dishwasher will not run promptly.
- Stainless flatware is loaded away from silver and visibly rusting items.
Never do
- Do not use the dishwasher when the item’s label or manual says to hand-wash it.
- Do not machine-wash sharp knives or hollow-handled utensils unless their manufacturer allows it.
- Do not leave salty or acidic residue on the surface while the item waits for a later wash.
- Do not let stainless steel touch sterling silver or silver plate in the basket because contact can pit the silver.
- Do not load it beside a visibly rusting steel item or cast-iron pan because iron contamination can leave rust stains.
Why those conditions exist
Passive film resists corrosion
A thin passive film on the steel surface provides corrosion resistance. For pieces approved by the manufacturer, a normal dishwasher cycle is an intended cleaning method.
Residue can cause pitting
Salt left on the surface supplies chlorides, and acidic residue can make local attack easier. If the passive film breaks down at a weak spot or crevice, small pits or rust-colored staining can develop.
Construction sets the limit
Dishwasher heat and detergent act on the whole product, while items can also strike each other during the cycle. Adhesives may loosen. Seals can fail, and knife edges may nick or dull.
Material vs. whole item
The common mistake is treating “stainless steel” as a dishwasher-safe label. It only identifies the metal, so the care instructions still control the decision for the finished product.
A plain bowl or measuring spoon is usually uncomplicated. Knives can lose edge quality, hollow handles may contain adhesive, and insulated pieces rely on seals that dishwasher heat or water can damage.
