Homemade, nontoxic cleaning agents are just as effective as their chemical-ridden competitors, and they provide the added benefit of not polluting the environment. You also save money, as homemade cleaning agents are nearly always cheaper than store-bought products. A homemade formula of vinegar and baking soda--both natural stain removers--cleans silver cheaply and effectively.
Boil 4 cups of water in a kettle.
Plug your sink, and then line the entire sink with heavy-duty aluminium foil.
Place your silver goods in the sink. Make sure that each piece is touching the aluminium foil.
Sprinkle the baking soda and salt directly on the silver. Make sure these ingredients are well-distributed on the silver.
Pour the vinegar on top of your silver products. Make sure they are evenly coated.
Add the boiling water. Allow the jewellery to sit for 15 minutes.
Put on rubber gloves and carefully remove the silver. Alternatively, you can wait for the water to cool, and remove your silver products then, without gloves.
Buff each piece of silver with a soft cloth for an intense shine.
