In this study, the effect of HCl acid solution on some carbonate stones from Turkey is investigated. It is known that stone plates used for outdoor and indoor covering applications can be been exposed to acid effects. For example, some chemical cleaning substances or drinks that contain acid can come in contacted with stone surfaces inside a building or acid rains outside can alter surface characteristics of stone plates. The calcite within the marble or limestone reacts with acid and is dissolved. In this way, it can be seen significant changes in the surface quality of stones. The surfaces of stone material losses its glossiness and its beauty.
