Gold is tough stuff and can handle being worn every day. You can use a mild jewellery cleaner and polishing cloth to bring out the shine in your solid gold. Regular cleaning will help keep it looking as good as new. You can soak diamonds overnight in a very diluted formula of an eco glass cleaner, then give them a little brush with a really soft toothbrush. Shine them up with a lint free cloth and they are ready to sparkle again.
