Clean discoloration of silverware using ultrasonic cleaners
by Christoph Schumacher on Mar 25, 2023
There are various ways to remove discoloration from silverware. An ultrasonic cleaner can help speed up the process and reduce laborious mechanical cleaning to a minimum. In general, there are different methods to clean silverware using ultrasonic cleaners. Since the discoloration is a chemical transformation of the silver into oxidation products, removal by the ultrasonic effect alone is usually not sufficient, and a few more tricks must be employed.
Here are some recommended methods:
Use a mixture of baking soda and water in your ultrasonic cleaner. Place the cutlery in the mixture and let it sit for about 15-30 minutes in the basket of the switched-on ultrasonic cleaner. If necessary, you can then rub off any remaining discoloration with a soft brush or cloth.
Place the cutlery on a piece of aluminum foil, which is placed in the basket of the ultrasonic cleaner. Fill the cleaner with a solution of water and salt. A sensible salt concentration is about one tablespoon of salt per liter of water. Turn on the cleaner for about five minutes. The chemical reaction that takes place between the aluminum and the salt can remove the discoloration on the silver. The aluminum foil will slowly dissolve due to this reaction and also due to the effect of the ultrasound. As a result, the water turns gray. Therefore, you will need to rinse the cutlery and rub it with a cloth afterward.
An ultrasonic cleaner generates sound waves that are capable of mechanically dislodging further dirt from the silver.
There are many other methods that can be found on the internet. Regardless of the method you choose, you should always rinse the cutlery thoroughly and dry it afterwards to ensure that no residue remains or stains form.
