Think of a soap, now add some mild abrasives, some cleaning agents, and a polishing agent. Now you get P21S Polishing Soap. This product is very unique and revolutionary. Safe for bare metals such as Stainless Steel, Aluminum, Brass, even Chrome. Simply dab the yellow sponge applicator in some water, dab it again in the polishing soap, then gently begin scrubbing the metal. You can feel and hear the product working. After a few minutes, wipe the product off with a clean microfiber cloth. The results will be short of amazing. The metal will have a clean, polished, and shiny look that use to be accomplished by using harsh chemicals. Another great feature of this product is its clean soap-like scent. Very pleasant while you’re working. Great product that works as advertised.
