**I. Why Do Stainless Steel Knives and Scissors Rust?**

Stainless steel is not entirely rust-proof; its resistance to rust depends on the chromium content. Chromium reacts with oxygen to form a protective chromium oxide layer, preventing internal metal corrosion. However, stainless steel knives and scissors can still rust under the following conditions:

1. **Damage to the Protective Layer:** Scratches from hard objects or exposure to strong acids and alkalis can damage the chromium oxide layer, leading to rust.

2. **Prolonged Contact with Corrosive Substances:** Substances like salt, acid, and fruit juices can corrode the stainless steel surface.

3. **Humid Storage Environment:** Damp environments accelerate metal oxidation, increasing the risk of rust.

**II. Usage and Maintenance Tips**

1. **Usage:**

* Avoid contact with hard objects to prevent surface scratches.

* After cutting acidic or salty foods, rinse and dry immediately.

* Do not use knives or scissors to pry hard objects, as this may damage the blades.

2. **Cleaning:**

* Rinse with water immediately after use and dry with a soft cloth.

* For stubborn stains, use a neutral detergent and avoid strong acids or alkalis.

* Ensure thorough drying after cleaning to prevent water spots.

3. **Storage:**

* Store in a dry, ventilated area to avoid humid conditions.

* For long-term storage, apply a small amount of edible oil to prevent rust, and clean before use.

**III. Rust Removal Methods**

If rust has already formed, try the following methods:

1. Use a soft cloth dipped in white vinegar or lemon juice to wipe the rust, then rinse with water and dry.

2. Use a specialized stainless steel cleaner, following the instructions.

**IV. Precautions**

* Avoid using hard cleaning tools like steel wool to prevent surface scratches.

* Do not soak knives and scissors in water for extended periods.

* Regular maintenance will extend their lifespan.
