1. Why does stainless steel scratch?

Although stainless steel is strong, it can still scratch due to the following reasons during daily use:

• Scratches from hard objects (such as collisions with knives and metal tools)

• Improper cleaning (using steel wool or rough cleaning cloths)

• Friction during transportation or installation

• Long-term wear (such as frequently used countertops and handrails)

Common Misconceptions:

• "Stainless steel can never be scratched."→ In reality, even 304/316 stainless steel can be damaged by external forces.

• "Small scratches don't affect use."→ However, deep scratches can damage the surface oxide layer, increasing the risk of rust.

II. 5 Effective Methods for Removing Stainless Steel Scratches

Method 1: Mechanical Polishing (Suitable for Shallow Scratches)

Tools:

• Stainless Steel Polishing Paste

• Soft Cloth or Polishing Wheel (Manual/Powered)

• Fine Sandpaper (600 grit or higher, for deeper scratches)

Steps:

1. Clean the surface, ensuring it is free of oil and dust.

2. Apply polishing compound and rub the scratched area with a soft cloth in circular motions.

3. For stubborn scratches, first lightly sand with fine sandpaper (600-1200 grit) and then polish.

4. Wipe away any residue with a clean cloth and inspect the repair results.

Suitable for kitchen countertops, sinks, and appliance surfaces.

Method 2: Baking Soda and Water Paste (Eco-friendly and Eco-Friendly)

Materials: Baking soda, water, and a soft cloth.

Instructions:

1. Mix baking soda and water (2:1 ratio) to form a paste.

2. Apply to the scratched area and rub gently in circular motions with a soft cloth.

3. Continue rubbing for 2-3 minutes until the scratch is lighter.

4. Rinse with clean water and wipe dry.

Advantages: Non-chemically corrosive, suitable for food contact areas (e.g., refrigerators, tableware).

Method 3: Professional Stainless Steel Repair Agent (Quick and Effective)

Recommended Products:

• 3M Stainless Steel Cleaner and Repair Agent

• Autosol Metal Polishing Paste

Instructions:

1. Shake the repair agent well and apply it to the scratch.

2. Use a microfiber cloth to wipe in the direction of the grain.

3. Repeat 2-3 times until the scratch disappears.

Suitable for: Deep scratches or large repair areas.

Method 4: Solder Fill (for Deep Scratches)

Suitable for: Industrial equipment, heavy stainless steel components.

Steps (Requires professional skills):

1. Clean and lightly sand the scratched area.

2. Use low-temperature solder to fill the indentation.

3. Polish until flush with the surrounding surface.

Note: This method is for professionals only; use with caution at home.

Method 5: Brushed Repair (Restoring the Original Texture)

Applicable Scenario: Brushed stainless steel (such as appliance panels and decorative panels).

Tools: Brushed stainless steel repair pen or brushed cloth.

Instructions:

1. Wipe in one direction, following the original brushed direction.

2. Avoid rubbing back and forth to prevent further damage.

III. How to prevent stainless steel scratches?

1. Use soft cleaning tools (such as sponges and microfiber cloths).

2. Avoid directly dragging metal objects (such as pots and knives).

3. Regular maintenance: Wipe with stainless steel maintenance oil monthly.

4. Apply protective film (suitable for high-wear areas, such as elevator panels).
