Updated: Nov 22

When it comes to natural solutions for restoring tarnished silver, diatomaceous earth (DE) is a surprisingly effective and eco-friendly option. Diatomaceous earth has a multitude of uses—from pest control to filtration—but its mildly abrasive texture also makes it ideal for polishing silver. This blog post will explain how diatomaceous earth can be used for cleaning silver, why it works, and the best practices to restore your silver pieces to their original shine.



 


What is Diatomaceous Earth?

Diatomaceous earth is a naturally occurring, soft sedimentary rock made up of the fossilized remains of diatoms, a type of microscopic algae. When ground into a fine powder, DE has a light, abrasive texture. It’s composed mainly of silica, which gives it a unique structure and consistency. DE has a variety of applications, but in this case, its gentle abrasiveness and absorbing moisture properties, makes it an ideal natural polish for tarnished silver.



 


Why Does Silver Tarnish?

Silver tarnishes due to a chemical reaction between silver and sulfur compounds in the air. This reaction forms a layer of silver sulfide on the surface, which appears as a dark or black discoloration. While this tarnish doesn’t damage the silver itself, it certainly dulls the shine and beauty of silver items. Over time, tarnish builds up, and regular cleaning is needed to keep your silver looking bright.



 


Why Use Diatomaceous Earth for Tarnished Silver?


There are several advantages to using diatomaceous earth for cleaning silver, including:


  1. Eco-Friendly: Unlike many silver polishes that contain harsh chemicals, diatomaceous earth is completely natural and biodegradable, making it safe for you and the environment.


  2. Non-Toxic: DE is safe to handle and odor free, and because it’s food-grade, you don’t have to worry about toxic residue left on your silverware.


  3. Gentle Abrasiveness: Diatomaceous earth is abrasive enough to scrub away tarnish without scratching or damaging the silver. This makes it ideal for antique and delicate pieces.


  4. Cost-Effective: Diatomaceous earth is affordable and widely available in stores and online. We offer a 2.5lb size that is perfect for this!




 


How to Clean Silver with Diatomaceous Earth

If you’re ready to restore the luster to your tarnished silver with diatomaceous earth, here are the steps you’ll need to follow.


Materials Needed:

  • Food-grade diatomaceous earth

  • A small bowl

  • Soft cloth or sponge

  • Water

  • Microfiber cloth for buffing


Instructions:

  1. Prepare a Paste: In a small bowl, mix a tablespoon of diatomaceous earth with just enough water to form a thick paste. This paste should be thick enough to stick to the silver without dripping.


  2. Apply to the Silver: Use a soft cloth or sponge to gently rub the DE paste onto the tarnished areas of the silver item. Make sure to rub in small, circular motions to cover the surface evenly.


  3. Let It Sit: For heavily tarnished items, allow the paste to sit on the silver for about 5–10 minutes. This resting period allows the diatomaceous earth to work on the tarnish.


  4. Rinse Thoroughly: Rinse the silver item under warm water, gently rubbing off the paste as you rinse. Ensure no residue is left on the item.


  5. Buff to Shine: Once rinsed and dried, use a microfiber cloth to buff the silver to a polished, shiny finish.



 


Tips and Precautions


  • Avoid Excessive Rubbing: Diatomaceous earth is abrasive, so you don’t need to use excessive force while polishing. A gentle rub will do the job without risking scratches.


  • Don’t Use on Silver-Plated Items: If the item is silver-plated, avoid using DE, as the abrasive action may wear down the plating over time.


  • Spot-Test: If you’re concerned about potential scratching, do a small spot test in an inconspicuous area before polishing the entire piece.


  • Store Silver Properly: To prevent tarnish, store your silver items in anti-tarnish cloths or sealed bags.



 


Alternatives to Diatomaceous Earth

While diatomaceous earth is effective, there are other natural alternatives if you prefer different methods. Baking soda, for instance, is also a popular choice for removing tarnish from silver. However, if you’re looking for a solution that is gentle and eco-friendly, diatomaceous earth remains an excellent choice.



 


Final Thoughts


Using diatomaceous earth to clean tarnished silver is a unique yet effective approach for those looking to restore their silver’s shine naturally. By following these simple steps, you can bring new life to your tarnished silver items without resorting to harsh chemicals. Eco-friendly, safe, and affordable, diatomaceous earth is a great addition to any household cleaning toolkit.
