Sterling Silver can be easily cleaned and polished using a simple cleaning cloth to keep your piece looking as new as the first day you take it home! To keep it safe from harm also make sure you store your Najo jewellery in a soft pouch or jewellery box. The nature of sterling silver is that it will tarnish and discolour over time. Exposure to moisture, humidity, acidity from skin, and exposure to such things as soaps and perfumes can all cause the silver to discolour. Regular cleaning though with a silver polishing cloth, and occasionally a metal cleaner or silver foam will keep your piece looking beautiful for years to come. Stainless steel jewellery can be easily cleaned with warm soapy water or a soft cloth.
