How to Remove Rust From Stainless Steel Knives

Stainless steel knives can develop rust stains.

Rust stains on stainless steel knives can be extremely frustrating. Sometimes you can remove the stains with mild dish detergent and warm water, but often they are more stubborn. Rust stains develop on stainless steel because of leftover food that is not washed completely away or by contact with other metal objects, particularly other pieces of stainless steel. If exposed to moisture for extended periods of time, stainless steel will also develop rust stains. You can remove the rust with some elbow grease, but take proper care of your stainless steel knives in order to prevent the stains from occurring in the future.

Things You'll Need

• Metal polish
• Soft, clean cloth
• Mild dish soap

Instructions

1. Put a small amount of metal polish onto a soft, clean cloth. You can also use polish designed specifically for stainless steel.

2. Rub the metal polish into the stain on the knife in the same direction as the grinding marks on the blade. Use a slight bit of pressure, but not too much. Be careful to rub in one direction only to avoid cutting yourself on the blade.

3. Repeat until the rust stain is completely removed. Depending on the severity of the rust stain, you may need to polish the blade several times.

4. Wash the knife in warm water with mild dish detergent.

5. Rinse the knife well with warm water.

6. Dry the knife thoroughly before putting it away.

Tips & Warnings

• Wash your stainless steel knives in warm, soapy water then rinse immediately after using them.

• Dry your knives thoroughly after washing them.

• Wash your stainless steel knives by hand instead of washing them in the dishwasher.

• If you do wash your knives in the dishwasher, remove them immediately after the cycle finishes and dry them. Also, do not allow them to touch other stainless steel cutlery. Place them in the top rack instead of the silverware basket.
