How to Polish Silverware with Baking Soda

Why Baking Soda Works on Silverware

Baking soda (sodium bicarbonate) is mildly alkaline and gently abrasive — properties that make it effective at breaking down tarnish (silver sulfide) on silverware. When combined with aluminum foil and hot water, it creates an electrochemical reaction that transfers tarnish off the silver without any scrubbing. Used as a paste, it polishes away light tarnish mechanically.

What You'll Need

• Baking soda
• Microfiber cleaning cloths
• Silver polishing cloth
• Aluminum foil
• Hot water
• A bowl or sink

Method 1: Aluminum Foil and Baking Soda (Best for Heavy Tarnish)

1. Line a bowl or baking dish with aluminum foil, shiny side up
2. Place silverware on the foil, ensuring each piece touches the foil
3. Sprinkle 2–3 tablespoons of baking soda over the silverware
4. Pour boiling or very hot water over everything until submerged
5. Watch the tarnish transfer to the foil — let soak 5–10 minutes for heavy tarnish
6. Remove with tongs, rinse thoroughly with warm water
7. Dry immediately with a microfiber cloth
8. Buff with a silver polishing cloth for extra shine

Method 2: Baking Soda Paste (For Light Tarnish and Spot Treatment)

1. Mix baking soda with just enough water to form a thick paste
2. Apply to the silverware with a soft microfiber cloth
3. Rub gently in long strokes following the grain of the silver — never circular motions which cause micro-scratches
4. Let sit 2–3 minutes for stubborn spots
5. Rinse thoroughly with warm water
6. Dry immediately and buff with a polishing cloth

Tips for Best Results

• Use the foil method for heavily tarnished pieces — it requires no scrubbing and is gentler on the silver
• Use the paste method for spot treatment or light tarnish
• Always dry immediately — moisture left on silver causes new tarnish quickly
• Finish with a silver polishing cloth to add a protective layer
• Never use baking soda on silver-plated items with worn plating — it can remove the remaining plating

Final Thoughts

The aluminum foil and baking soda method is one of the most effective and gentle ways to remove tarnish from sterling silver at home. It requires no scrubbing and works through chemistry rather than abrasion. Finish with a silver polishing cloth for a brilliant shine.
