Brass
The best way to keep your brass looking new is to store it in an air-tight container, keep away from moisture and chemicals, and clean regularly. To clean your brass you can use over-the-counter products such as Brasso, or you can use a variety of natural cleaners such as lemon and salt, plain old toothpaste, or even ketchup for a quick shine in a pinch.
Gold Filled
Gold filled does not de-laminate or peel like plated or "dipped" products. Nor does it tarnish as readily as silver. Many owners find that they never have to clean gold-filled items at all. However, from time to time your jewelry may become dirty from everyday wear. To clean gold-filled it is best to use mild soap and water. Hot weather and water will not damage the material.
Gold Plated
The number one rule for cleaning gold plated jewelry is to never scrub it. It is also very important to not expose gold-plated jewelry to water or chemicals. Should your piece become tarnished or dirty, you can clean it with a cotton ball or a very soft cloth to remove any dust and dirt. Gently rubbing the surface of your gold plated jewelry using a soft jewelry cloth also helps restore shine. If your jewelry needs more cleaning you may clean it with warm, soapy water and dry thoroughly.
