Toothpaste, why you shouldn’t use it to clean your Jewellery

It is a common myth that toothpaste is a good way to clean your jewellery. This is actually false. Toothpaste can damage your diamonds, gemstones, gold and silver. Toothpaste is abrasive and has a hardness of around 3/4 on the Mohs Scale of Hardness. Metals such as gold and silver are softer, so toothpaste can actually scratch damage your gold and silver jewellery. Not to mention, the chemicals in the flavour oils used in toothpaste are corrosive to metal.

Some gemstones have a hardness a slightly higher on the Mohs scale, but they can still get surface abrasions if toothpaste is used to clean them. Pearls and opals should never be touched by toothpaste; it can destroy their colour and luster. So it is best to not use your toothpaste, and stick with a jewellery cleaner made to clean your specific jewels.

Precious stones are very soft and can be easily damaged by the toothpaste. The best way to clean these delicate items is to buff them with a silver polishing cloth
