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
Why: Heat and moisture cause warping, cracking, and bacterial growth in splits.
Do this: Hand-wash, air-dry upright, condition monthly with mineral oil.
