Apply it liberally to the entire surface of the component then wipe off with a microfiber rag. Wipe using the microfiber rag in the direction of the grain in the brush steel. The FLO Grills H2O formula helps to bring out the shine as well as repelling dust.
Environmental factors to consider are salt water areas and pool area. Never keep pool chemicals of any kind in your island as it will cause scaling and corrosion. Pool water splashed on the stainless steel by any means will also leave discolored spots on the SS. Salty water can do the same as pool water on contact with the surface of the stainless steel. It is recommended to have a cover on the components if you can or even have a cover made to go over the entire island. If you get spots of discolored areas or small rust spots clean the area with soap and water, then dry. Something that have been used to remove spots or rust are naval jelly and bar keepers friend for SS. Remember, if you use any products to clean a spotted area you need to clean the entire surface the same or it can discolor unevenly.
