The kitchen is the heart of the home, but it can also be a breeding ground for harmful bacteria. Whatever type of countertop surface you have, take the time to regularly disinfect it. All you have to do is wash it and scrub away visible marks and dirt with warm, soapy water. Then dry it with a microfiber towel; the millions of microscopic fibers literally grip onto germs and bacteria. Then do one more thing: Spray rubbing alcohol all over and let it naturally evaporate. You can also use this same cleaning method for cutting boards.
