The Basics of Jewellery Care: Clean your Jewellery regularly
For years of wearability, jewellery should be cleaned frequently. It is not advisable to let a thick coating of black tarnish build up on your jewellery as it can eventually eat away at metals and create permanent damage to the piece.
There are a variety of methods for cleaning Jewellery. For light tarnish a polishing cloth is the least abrasive method. There are two types of polishing cloths, plain and with rouge embedded in them.
A plain cloth is perfect for weekly cleaning of your pieces. It must be a cloth designed for cleaning jewellery as the fibers in these cloths will not scratch the metal.
You would be surprised that some cloths can actually put scratches into silver and gold jewellery as they have hardness greater than the metals. Use a polishing cloth by rubbing it over the surface of your jewellery. Chains can be pulled through the cloth as you pinch them lightly between the cloth in your fingers.
For a slightly heavier cleaning use a cloth embedded with rouge. Rouge is a polishing compound used in the final stage of finishing jewellery. It can be used on all metals and on most gemstones (check with a jeweller first). After rubbing your jewellery with the rouge embedded side of the cloth rub the jewellery with the non-rouge side of the cloth to remove the compound. Wash your hands well after touching rouge as it is a strong chemical and can easily transfer to other items you subsequently touch.
If you find that the cloths are not removing the tarnish the next step is a metal cleaner that is rubbed on with a sponge under running water. Polishing compounds such as this remove a thin layer of the metal in the process of removing the tarnish. Be careful if you are cleaning plated jewellery as repeated polishing will remove plating over time.
