Silver is dishonourable for dulling, going black and brown at the edges. This is caused by contact to the air, which shows in the copper content that exist in genuine silver oxidizing on the surface.
There are more than a few ways to spotless silver. Proprietary brands such as Goddard is Silver Dip are outstanding - just a few seconds dip and then a warm wash with a mild detergent and then pat dry with some kitchen paper towel. With these dips, though, you must not dip pearls - they will be irreparably injured. You can clean the silver around the pearls by dipping a flexible toothbrush into the dip and then polishing the silver, avoid the pearls. Don’t clean your teeth with the toothbrush afterwards!
But talking of toothbrushes, another system of attack silver is to use toothpaste. Simply rub the toothpaste all over the silver jewellery and wash it off. You won’t get such outstanding results on really blackened silver, as with the dips, but for normal cleaning, it's a lot cheaper.
Another way of observance your silver jewellery clean and keep away from having to option to such methods to clean it is to put a piece of chalk in the box alongside it - the chalk absorbs the moisture in the air that as I said earlier, affects the silver. Along the same lines is the method of packaging up your silver in acid-free tissue paper until you want to utilize it. This is what we do with nearly all our silver sales - if a bride-to-be buys a crown and her wedding is not for a few months, we tell her to stay the crown wrapped up until the big day!
Gold jewellery, though retaining its shine longer than silver still can go dull and dirty. It can be quite a surprise after cleaning to appreciate just how dirty it had become. Again with gold, I would recommend jewellery dip even the same silver dips I mention before will also work on gold. The dips will not damage gemstones or crystals so you will be safe dipping those.
Pearls, as I talk about before are the exemption. They need very gentle cleaning, as the surface is subtle and can easily become scuffed and lose their lustre. Also beware perfume! The alcohol happy of perfume can have an effect on pearls.
Pearls are best cleaned using warm water and a gentle detergent appropriate for woollens and then quietly dried with a soft cloth. Store pearls in a soft pouch away from other jewellery to keep away from the pearls flattering scratched.
