Alkaline cleaners (strippers) for Marble
Most stones are sensitive to both acidic and alkaline detergents. Acids spoil the stone, dissolving calcium, which binds its crystals (which is especially dangerous for marble, limestone, travertine and other types of stone, which contain calcium).
Alkaline agents usually do not damage the stone as acids, however, left on the surface for a long time, they can cause the stone to fade.
Therefore, it is recommended to use pH neutral detergents for daily stone care.
Alkaline cleaners (strippers) are used to clean highly contaminated surfaces, and after using them, the stone surface is recommended to be thoroughly washed with a pH neutral detergent to neutralize the reaction. When using strippers, it is not recommended to use hot water, because high temperature speeds up reaction, which can also damage the stone.
It is important to check each detergent on a small area before applying it to whole surface.
