Polishing silver

Have you ever wanted to polish your silver in a more archival, museum quality way? This is the baking soda method.

I first heard of the tin foil and baking soda method in a question and answer portion of a podcast from the National Museum of Australia, so naturally, I couldn’t find it again when I looked for it. But if it’s good enough for a museum, it’s good enough for me.

I used a nicely written post by apartmenttherapy.com as my starting point. I’ve tried this a few times, with somewhat variable results – possibly because of the quality of silver versus the amount of tarnish. What I like about it is it’s rather fast, and doesn’t leave residue. I’ve have noticed there are more archival silver polishes out there, although I haven’t tried them (see the Carr McLean Archival Supplies and Equipment catalog).

What you need are:

  • Aluminum foil
  • Plastic, glass, or aluminum tub
  • 4 cups boiling water
  • 4 tablespoons baking soda
  • 4 tablespoons salt
  • 2 cups white vinegar
  • lint-free cloth for polishing
  • warm, soapy water

The process

  1. Boil the water. It will activate the baking soda and starts the process of transferring the tarnish to the foil.
  2. While the water is coming to a boil, add the dry ingredients into the tub. When you add the vinegar there will be a reaction (science fair volcano). Be careful. The vinegar speeds the tarnish removal process along.
  3. Carefully pour in the boiling water, making sure all of the pieces are touching the foil directly. It starts to work immediately, but heavily tarnished pieces may take longer.

  4. Use the lint-free cloth to polish up the silver and buff off any remaining spots.
  5. I find the silver immediately starts to fade, so I wash them in a mild detergent to take any residue off, and buff them while drying to bring up that nice shine.
  6. If there are stubborn bits of tarnish left, I will hit them with some commercial silver polish (for shame!), and rewash them.
