Carefully brush with a soft bristle brush or an old toothbrush. After brushing, simply rinse with lukewarm water and allow to dry. Grease can be removed from gold jewellery by dipping it into plain alcohol. When not wearing jewellery, store it in soft cloth pouches, soft cloth wraps or plastic zip-lock bags. Chains should lie flat to avoid kinks.
Gold is strong, but can still be scratched.
So, avoid placing pieces atop each other in a jewellery box or drawer. Store your ornaments in a dry place. Avoid extreme temperatures. Always store jewellery in separate pouches or wraps. Don't stuff them into your jewellery box.
