We like to use WD–40. It is not only very easy to use, but is also quick and very effective. All you need to do is coat the gold and brass lamp with a layer of WD–40, which is a great to clean brass and let it sit for about 15-30 minutes. Take a clean cloth and rub the lamp in circular motions drying and buffing it up.
It is true the vinegar is acidic and can ruin brass if the solution is too strong with vinegar and the brass allowed to remain too long in the solution. If the solution turns blue, copper is being removed from the brass and the loss of copper will make the brass softer therefore weaker.
Brass that is only slightly tarnished can be polished successfully with many of the off-the-shelf cleaners and compounds sold at groceries and department stores. Lemon juice and salt mixed together also will do a great job. Once again, after the brass is shiny, be sure to wash it with soap and water.

Lemon –squeeze half a lemon onto a clean cloth and sprinkle salt on top. Rub the cloth over the surface of the brass and then rinse it off. This will really cut through the tarnish but don’t leave it too long. This is a good way of cleaning doorknobs and knockers that you can’t easily soak.

How Does This Work? Cola cleans brass because it’s mildly acidic. Here’s what happens: When brass or another metal alloy becomes tarnished, this means that there has been a chemical reaction between the oxygen in the air and one of the metals in the alloy.
Since hydrogen peroxide fights bacteria as an oxidizing agent, it makes sense that it could be used to oxidize metal as well. This means you can use hydrogen peroxide on metals like brass and copper to quickly make them look rusted for a unique, antique look.
