How to Clean Silver Jewellery and Cutlery — Toronto Home Guide

Silver tarnish is a chemical reaction between silver and sulfur compounds in the air — it's not dirt and doesn't respond to regular cleaning. The right method removes tarnish chemically or mechanically without damaging the silver.

Baking Soda and Foil Method (Best for Heavy Tarnish)

This electrochemical method transfers tarnish from the silver to the aluminum foil — fast and highly effective for heavily tarnished pieces:

1. Line a bowl or sink with aluminum foil, shiny side up
2. Place the silver pieces on the foil so they contact it directly
3. Bring water to a near-boil and pour over the silver to cover
4. Add 1 tablespoon of baking soda and 1 tablespoon of salt per litre of water — the mixture will fizz
5. Let sit 5–10 minutes — you will see the tarnish transfer from the silver to the foil
6. Remove with tongs (the water is hot), rinse with clean water, and dry thoroughly with a soft cloth
7. Buff dry with a microfibre cloth for a polish

Dish Soap and Warm Water (Light Tarnish)

1. Wash in warm water with a few drops of dish soap and a soft cloth
2. Rinse and dry immediately — leaving silver wet causes additional tarnishing
3. Buff with a dry soft cloth

Silver Polishing Cloth

A jewellery polishing cloth (available at pharmacies and jewellery stores) is the fastest option for small pieces and light tarnish — rub gently in straight lines, not circles. These cloths are impregnated with a mild polishing compound that removes tarnish without liquids.

What to Avoid

• Toothpaste — too abrasive for silver; causes micro-scratches that dull the finish
• Ultrasonic cleaners for pieces with gemstones — can loosen settings and damage certain stones
• Soaking silver-plated items for extended periods — water penetrates through plating chips and causes corrosion underneath

Preventing Tarnish

• Store silver in airtight bags or anti-tarnish pouches — most tarnish comes from air exposure
• Include a chalk stick or silica gel packet in storage to absorb moisture
• Keep away from rubber (rubber contains sulfur compounds) and humid environments like bathrooms
