You need an ordinary limescale removal, metal and soft sponge, a polishing cloth! Spay the sink thoroughly. Clean first with the soft sponge. When limestone has formed a hard surface then you need to use the metal sponge. Then wash thoroughly with water. Polish with a dry microfibre cloth to dry and avoid the appearance of lime spots again. Do this deep cleaning at least once a week.
