Things You Absolutely Should Not Put in a Dishwasher

Your dishwasher is a modern miracle—but it’s not a one-size-fits-all cleaning machine. The combination of scalding water, harsh detergents, and high-pressure jets can ruin certain items quickly, sometimes permanently.

Here’s a clear, practical list of kitchen essentials that belong only in the sink—plus what to do instead.


🚫 10 Things That Never Go in the Dishwasher

1. Sharp Knives (Chef’s, Paring, Steak)

  • Why: High-pressure water dulls edges; detergent corrodes blades.
  • Do this: Hand-wash with mild soap, dry immediately, store in a block or sheath.

2. Cast Iron Skillets & Pots

  • Why: Strips seasoning, causes rust, and ruins the natural non-stick surface.
  • Do this: Rinse with hot water, scrub with brush (no soap!), dry on stove, oil lightly.

3. Wooden Utensils, Cutting Boards & Bowls
