The first step
The first step by building cleaning service in any floor maintenance program is finding out what type of stone you’re dealing with. Stone floors are broken down into one of two categories: stone that contains calcium and those that do not contain calcium. It is important to note that acids will attack and etch stone that contains calcium. If the floor is not coated on the surface, a simple test can determine what type of stone you are dealing with. Place a drop of hydrochloric acid in an inconspicuous area and watch the reaction. If the acid fizzes the stone contains calcium. If there is no reaction, the stone is most likely granite, slate, sandstone or some type of ceramic that has been designed to look like natural stone.
