The kitchen sink should be one of the cleanest places in the home, which means it should be cleaned every day. However, simply rinsing your sink with water does not adequately get rid of germs and bacteria. To clean a stainless steel sink effectively, use a soft wash cloth or non abrasive sponge with a cleaner. Never use a metal scrub brush as this can leave scratch marks. Before cleaning, wash and remove any dishes inside the sink and get rid of any solid food residue Next put a small amount of cleaner on to the sponge and wipe the sink in the direction of the polish marks. When finished, wash the cleanser off and use a clean towel or cloth to dry the sink. If you prefer to use natural cleaners, there are plenty of inexpensive natural alternatives. Vinegar and baking soda are very effective.
