LIMESTONE
Limestone is a porous material. It is a soft stone susceptible to etching and staining if you don’t protect it carefully.
In general, you must avoid acid solutions coming into contact with limestone, applies to cleaning products as well (vinegar, lemon juice or other cleaners containing acid).
Wiping the surfaces with warm water and a nonabrasive sponge or soft cloth is the best method for cleaning but will not remove etching or stains that have had time to permeate the surface.
