Rojo Alicante Marble is a famous red marble from Spain. It has a deep luxurious look but like any other marble, if it is cared for improperly, it can be damaged quickly.
This photo shows the damage caused by using the wrong cleaners.
This is a great photo for two reasons. We hear folks in Pittsburgh say that they think hard water caused the damage to their stone. Hard water dose cause damage but its not the kind of damage that we regularly see, like in the upper photo, that has run marks in the stone. In the photo bellow notice the build up in the grout. This very hard layer almost like another layer of stone is caused by the hard water deposits.
Also hard water deposits along the base of the shower.
