stone maintain materials
 Natural stone is an exciting material with its physical characteristics of textures, its palette of colors and distinctive luster communicates permanence, integrity, quality and elegance. There is a certain magic about stone that can not be reproduced by any other material.
However, natural stone bears natures many complexities and shows large variations in its absorption, density and hardness. These have an important impact on how to protect and preserve the appearance and beauty of stone.
All natural stone is porous, which means water, spaghetti sauce, cooking oil and other liquids could seep into and stain it. In addition, acids—whether found in citrus fruits or household cleaners—have a corrosive effect on stone.
