1. What It Is
-
A traditional, chemical-free method to remove silver tarnish.
-
Uses baking soda, aluminum foil, and hot water.
-
Works through a chemical reaction called ion exchange, transferring sulfur from silver to aluminum.
-
Preserves silver better than abrasive polishes.
2. Why It Matters
-
Gentle & safe: No harsh chemicals, so it doesn’t wear down silver.
-
Eco-friendly: Ingredients are biodegradable and inexpensive.
-
Accessible: Most households already have what’s needed.
-
Historical roots: A method passed down through generations, proven over centuries.
3. The Science Behind Tarnish
-
Tarnish: Silver reacts with sulfur in the air → forms dark silver sulfide coating.
-
Reaction: Aluminum + baking soda + hot water removes sulfur without scraping off silver.
-
Result: Clean, restored shine.
