It&#39;s just the natural salts coming through and although it looks unsightly I&#39;ve never heard of damage. Is it on the floors or walls and is it marble or another material. You can actually saturate it (it&#39;ll take a few trips) with water and agitate to draw the excess salts out or if it&#39;s a material that won&#39;t isn&#39;t acid sensitive use Limescale remover from Prosco or a mild acid.<br>
