Cleaning zinc, like on a cast zinc table, cast zinc bar top, or cast zinc counter top is easily manageable and can usually be done without the use of special chemicals or supplies. Over time, zinc may appear chalky or white through the natural oxidation process. Simple soap and water will work in most cases. After the cleaning process is complete is generally recommended to use a wax or other sealant to help protect and make the surface more resilient to further oxidization.
