There’s nothing worse then pulling a cherished piece of silver jewelry out and finding it’s turned black, grey, white or yellow. Trying to figure out how to clean silver it can be tough.That colour is called tarnish and it’s the bane of any silver-lover.
I love making sterling silver jewelry in my spare time. Occasionally I take on custom-made jewelry requests. But I recently had a customer write me to say a necklace I’d made for him had turned black after just a couple weeks. He was surprised and thought something was wrong with the piece. Though it can look unsightly if not cared for properly, tarnish is a normal and natural process with sterling silver. But once tarnish or blackening is there, how can you clean silver?
What causes Tarnish?
When silver tarnishes, it’s a surface discolouration caused by the interaction of oxygen (air) with the silver. As the British Assay Office explains it, “silver naturally interacts with oxygen and sulphur-bearing pollutants to create silver sulphide, resulting in a visible discoloration of the metal’s surface. Silver tarnishes in environments containing various sulphuric gases, even in very low concentration. The amount of tarnishing is determined by the relative humidity, ambient temperature, gas concentration, and the length of time the silver is exposed to the gases.”
With sterling silver this process is normal, natural, expected, and yes, it can occur relatively quickly.
Many things can speed tarnish; air pollution, the minerals in your water (and as such, wearing your silver jewelry in the shower can speed this process too), living or working near a chemical, electric or manufacturing plant, or even in proximity to a gas starion are all things that can cause discolouration more quickly.
Recent studies have shown tarnish develops microscopically within hours of being cleaned and exposed to air again. You may not see it on the piece for several days or weeks, but it’s there, and will show up as a black residue on a polishing cloth.
How to clean silver
A great way to keep seldom worn jewelry clean (and silverware if you have it), is to store sterling silver in a ziplock bag with all the air squeezed or rolled out of it. You can wrap it in a soft cloth first too. Oxygen and thus tarnish may still seep in and can still cause blackening especially if the pieces are stores for long periods of time, but it should keep things to a minimum. Another great way to keep jewelry tarnish free? Wear it! Constant contact with the silver keeps tarnish from building up.
Chemicals can cause tarnish
Now, she actually liked this look and referred to it as ‘edgy’, so she’s leaving them as they are for now. If she did want them restored it should be a relatively simple process of buffing the chemical scarring off the surface layer, and exposing clean shiny silver beneath.
Don’t experiment with cleaning silver using household cleaners!
But this also serves as a leaning moment; only soap and water, silver polish, or a silver polishing cloth should be used to clean your silver jewelry. Many household cleaners and chemicals can alter your precious silver. In fact, I once had a ring turn bronze after accidentally spritzing window cleaner on it, and had other silver turn grey by getting baking soda onto it. That too buffed out, but you’ll want to be careful with your jewelry. Chemicals can also permanently damage certain stones like topaz, opal and more, so don’t experiment; you run the risk of really doing permanent damage.
How to Clean Silver and Remove Tarnish-> Get this Inexpensive Polishing Cloth
If you do find some discolouration of your silver, you can remove it with a silver cloth (brand names include Sunshine Cloth, which is available inexpensively from me, HERE or HERE). If that won’t work, stop while you’re ahead and take it to a pro for professional help.
A Note about Grocery Store Silver Cleanser
I’ve purchased cleansers from grocery stores that just don’t work. If you’re going to get a cleanser from somewhere other than a jewelry professional, test it first on a small area. If the cleaner doesn’t remove tarnish instantly, it’s not working. Proper liquid silver cleaners will remove all tarnish in about 3 seconds. If you need to soak, or scrub, stop using it, rinse your silver, and return the cleaner to where you bought it and get your money back. (Keep your receipt!)
