Can stainless steel go in the dishwasher?

Stainless steel is prized for its durability, sleek look, and protective chromium oxide layer. Yet, questions still arise about whether it’s truly dishwasher safe—especially when different grades of stainless steel and different cookware designs come into play. In this article, we’ll clarify the nuances of washing stainless steel in the dishwasher by cross-referencing the facts below, so you can care for your kitchen items with confidence. We’ll also share some handy tips for hand washing and suggest a gentle, eco-friendly dishwashing detergent alternative for those who want to avoid harsh chemicals.

What is Stainless Steel?

Stainless steel is a steel alloy containing iron, chromium, and often nickel. The chromium forms a thin, invisible film of chromium oxide on the surface that protects against rust and corrosion. However, not all stainless steel is created equal. Different grades such as 18/8, 18/10, or 18/0 vary in their nickel and chromium content, which can influence both their durability and dishwasher safety:

• 18/10 and 18/8: Often used for cutlery and stainless steel cookware like pots and pans. They contain higher nickel content (especially 18/10) to enhance corrosion resistance but can be more prone to surface damage in certain conditions—like overly hot dishwasher cycles or exposure to strong detergents.
• 18/0: Contains no nickel, making it more likely to be fully dishwasher safe since the risk of corrosion or surface damage is lower. It’s frequently used for items that aren’t exposed to direct heat (e.g., some cutlery).

Can Stainless Steel Go in the Dishwasher?

Generally, Yes—But Check First

Many stainless steel pots and pans in the dishwasher will come out just fine. However, always check the manufacturer’s label or product specifications:

1. “Dishwasher Safe” Markings: Look for this explicitly on packaging or the cookware itself.
2. Grade of Stainless Steel: If you own 18/10 or 18/8 cookware, extra care is advisable. If it’s 18/0, it’s generally less prone to issues.
3. Clad or Multi-Layered Cookware: Stainless steel-clad items (e.g., pans with layers of aluminium or copper) can be more vulnerable to harsh chemicals and high heat in your dishwasher.

How to Clean Stainless Steel in the Dishwasher

1. Rinse Off Food Particles: Scrape or rinse off residue to avoid baked-on messes that can lead to discolouration or spotting.
2. Avoid Harsh Detergents: Strong detergents may dull or etch the protective chromium oxide layer. For a gentler alternative, try Pure Suds Dishwashing Sheets, which are free of harsh chemicals and kind to both your cookware and the planet.
3. Choose the Right Rack: If the cookware is smaller or has plastic components, place it on the top rack to shield it from higher heat at the bottom. Larger pots or pans can go on the bottom rack, just ensure they aren’t blocking the spray arms.
4. Select an Appropriate Cycle: Some dishwashers have a dedicated “pots and pans” cycle. If not, opt for a normal or gentler wash to avoid extremely high heat.
5. Dry Immediately: Once the cycle finishes, remove and thoroughly dry with a soft cloth to prevent water spots and maintain shine.

Stainless Steel Items Needing Extra Care

• Heavily Insulated or Coloured Items: For instance, stainless steel water bottles with insulation or paint coatings may lose their seal or become discoloured from dishwasher heat. In these cases, it’s safer to hand wash.
• Stainless Steel-Clad Pots & Pans: While typically advertised as dishwasher safe, using a high-heat cycle repeatedly can dull the finish or cause discolouration over time. Occasional hand washing helps preserve their shine and extend their lifespan.

How to Clean Stainless Steel Water Bottles

If your water bottle is uninsulated and unpainted, placing it on the top rack of your dishwasher (cap removed) can be fine. Otherwise, it’s best to wash by hand with a mild detergent, rinse thoroughly, and allow it to air dry upside down or dry it with a cloth.

Hand Washing for Stainless Steel

If your items aren’t clearly labelled “dishwasher safe,” or if they are showing signs of dullness or rust spots, hand washing is a safer route:

1. Gentle Cleanser: Use a mild dishwashing detergent dissolved in warm water.
2. Soft Sponge: Never use a scouring pad or steel wool on stainless steel pots. This can scratch the surface and compromise the protective layer.
3. Rinse and Dry Immediately: Avoid leaving stainless steel items to air dry for prolonged periods; water spots or mineral deposits can form. Wipe them clean with a soft towel.

Common Dishwasher “No-Gos”

While stainless steel is usually safe, certain metals are best kept out of your dishwasher:

• Cast Iron: The seasoning can be stripped away, leading to rust.
• Carbon Steel: Similar to cast iron, it can rust if the seasoning is removed by strong detergents.
• Aluminium: May become discoloured or pitted, especially if not anodised or if labels don’t specify dishwasher safety.

Keeping these out of the dishwasher ensures your cookware stays in top condition.

Final Thoughts

So, can stainless steel go in the dishwasher? Absolutely—just be aware of the grade of stainless steel you own, check for “dishwasher safe” labels, and steer clear of harsh chemicals that can damage the finish. For items that are more delicate—like insulated bottles or high-end 18/10 pans—hand wash them occasionally to maintain their lustre. If you do opt to put stainless steel cookware in the dishwasher, remember to rinse off food particles, place them correctly, and dry immediately to avoid water spots.
