Never use these 4 things to clean your jewelry.
Baking soda is abrasive, which is why it’s great for cleaning sinks and toilets, but that abrasive quality can scratch gemstones and precious metals. So steer clear when it comes to cleaning jewelry.
Toothpaste is just as bad as baking soda for obvious reasons. First of all, it usually has baking soda in it. If your toothpaste doesn’t have baking soda in it, there’s some else abrasive that’s helping to scrub your pearly whites. Really, a good rule for jewelry cleaning is to avoid anything abrasive.
Plus, if you’re using a whitening toothpaste those whitening agents can also damage your jewelry.
Boiling water might sound like a good idea, after all, it’s just water. The problem isn’t the water, it’s the temperature. Cleaning your ring by dropping into a bath of boiling water can cause the metal to expand and contract which can loosen gemstones. The boiling water can also cause cracks and fractures to form in gemstones. Bottom line. Don't do it.
From rubbing alcohol to vodka, keep it away from your jewelry. Alcohol can dry out the natural oils in gemstones like opals and emeralds, which again, can cause them to crack.
