Article in English: Fake or impure metals will deteriorate quickly if not using the correct polish.  You can buy polish for either gold or silver items in many jewelry or department stores. Keep in mind that some regular jewelry cleaners, usually meant for the real deal, are too harsh to use on costume pieces. Simply soak the piece of jewelry in the polish for no longer than 30 seconds, then remove and wipe it gently to avoid scraping or bruising the jewelry. You might want to use a toothbrush after dipping it into the solution. Then take a small bowl, and pour the alcohol into it. Soak the jewelry in it for half an hour.  Then take the jewelry out, and wipe off any excess alcohol on it. Leave it out to dry for 15 minutes. If every part isn’t clean, wipe it with an alcohol wipe or repeat the process. You could put your earrings in peroxide, and let them soak at least 2 to 3 minutes. The peroxide might bubble or fizz, which means your earrings are really dirty, and you should probably leave them in longer. If it looks like you are rubbing off more of the finish than the gunk, then stop. You may be scrubbing too hard. Rub gently so you don’t mess up the finish. After applying the mixture and cleaning everything off, immediately rinse the piece off in cool water. Rinse just enough to get the soapy water solution off of the jewelry.  Dry it with a blow dryer. Immediately after you rinse off your jewelry, place it on a towel to soak up any excess water. Blot away excess water with the towel. Then, set your blow dryer to a cool setting, and use your blow dryer to quickly dry the jewelry. Move your blow dryer around the piece to distribute the air. Drying it quickly makes it less likely to rust and develop water spots. Continue drying the jewelry with the blow dryer until it is completely dry.  Try not to hold the blow dryer directly above areas with gemstones for long periods of time especially if you decide to use a warmer setting. You don’t want the heat from blow dryer to melt the glue holding them down.
