Everyday cleaning of zinc can be done with a sponge or soft towel and mild dish soap. Any cleaner that contains citric acid, ammonia or other harsh chemical should be avoided to reduce any unwanted aging or spotting.
Occasional use of abrasive side of sponge can be good to help remove any built up oxidation that forms naturally on the metal.
It is important to remember that the zinc can be clean but still have spots on it. If you would like to remove the spots, please see the polishing section.
You are welcome to add a wax or polish to the metal to help give it a shine and add some resiliency to the reactions. Keep in mind however, like waxing your car, it is not a permanent sealer.
