Why Does Stainless Steel Cutlery Turn Black?

Stainless steel contains chromium, which forms a protective layer against rust. However, it’s not invincible! Here’s why your cutlery might darken:

1. Heat Damage: High heat (e.g., dishwashers, direct flames) breaks down the chromium layer.
2. Hard Water: Mineral deposits from tap water leave chalky residues.
3. Acidic Foods: Tomato sauce or citrus juices corrode the surface.
4. Chlorine Exposure: Bleach or pool chemicals cause pitting and discoloration.
5. Dishwasher Damage: Dishwashers can cause stains and discoloration.
6. Oxidation and Tarnishing: Stainless steel resists rust but may tarnish.

How to Prevent Stainless Steel Cutlery from Turning Black

1. 🚫 Hand-Wash Instead of Using the Dishwasher

• Use mild dish soap (Seventh Generation Dish Soap, $4.99) and lukewarm water.
• Scrub gently with a soft sponge, following the grain of the metal to avoid micro-scratches.
• Rinse thoroughly to remove soap residue.

Pro Tip: If you must use the dishwasher, place cutlery in a dedicated basket to minimize contact with other metals (like aluminum), which can trigger chemical reactions.

• Buff in the direction of the grain to add a subtle shine.

Pro Tip: For extra protection, apply a drop of food-safe mineral oil to the dried surface to repel water.

3. 🧴 Avoid Abrasive Cleaners or Tools

• Use non-abrasive sponges (Scotch-Brite Non-Scratch Scrub Sponge, $3.99) or soft cloths.
• For stuck-on food, soak cutlery in warm, soapy water first to loosen residue.

Avoid:

• Bleach, chlorine-based cleaners, or scouring powders like Comet.

4. 🗓️ Monthly Baking Soda Maintenance Soak

1. Fill a basin with 1 quart of warm water.
2. Add ¼ cup of baking soda (Arm & Hammer Baking Soda, $2.49).
3. Soak cutlery for 15–20 minutes.
4. Rinse and dry thoroughly.
