Cleaning jewelry with foil involves a simple chemical reaction that removes tarnish. Here's a breakdown of the process:
-
Prepare the Items: Line a bucket, tub, or pot with aluminum foil, shiny side up.
-
Place the Jewelry: Put the jewelry you want to clean inside the foil-lined container, ensuring it touches the foil.
-
Add the Cleaning Solution: Heat enough water to completely cover the jewelry. Carefully pour the hot water over the jewelry and add 1 cup of baking soda per gallon of water. For smaller amounts use ratios like 1 tablespoon of baking soda per cup of water.
-
Soak: Allow the jewelry to soak in the solution for up to 30 minutes, depending on the level of tarnish. You may see bubbles and a sulfurous smell – this is the tarnish being transferred from your jewelry to the foil.
-
Rinse and Dry: Remove the jewelry from the solution. Rinse it thoroughly with water and dry it with a soft cloth.
Why this works:
This method utilizes a chemical process called ion exchange. The tarnish (silver sulfide) on your jewelry reacts with the aluminum foil in the presence of hot water and baking soda. This process transfers the sulfur from the silver sulfide to the aluminum, effectively cleaning the jewelry.
Important Considerations:
- Gemstones: This method is generally safe for jewelry without delicate gemstones. Some stones might be damaged by the baking soda and hot water. Avoid this method for opals, pearls, emeralds, and other porous or delicate gems.
- Materials: This method is best suited for sterling silver. Be cautious when using it on other metals, as it could potentially cause damage.
- heavily tarnished jewelry: Severely tarnished items might require a longer soaking time or a repeat of the process.
- Stubborn spots: for the best results, follow up with polishing with a suitable jewelry cloth to remove persistent tarnish.
