Luckily the solution is quite easy, and most people will probably already have all the needed ingredients at home. All you need is a glass of beer. Simply put your gold jewelry in a glass or bowl of beer and let it sit for about ten minutes. Once the ten minutes have passed, take the jewelry out and dry it with a clean kitchen towel or cloth. You will see that your jewelry will shine like never before. It will have returned to its original colour and look new again.
