have a travertine dining room table. One of our cats got sick on it the other
night. The next morning when we cleaned up the vomit, because of the acid in
his stomach, it left a small stain about the size of a dollar bill. Is there a
way to polish this back up?
A: You are correct in that the acids from the vomit have
caused the damage to your table. However, it is not a stain, but an acid etch. Your
travertine has been etched by a chemical reaction between the calcite (the main
ingredient in travertine) and the acid from the vomit.
If the polishing doesn’t work, you need to contact a
stone restoration contractor.
Good luck with
CALCITE A common crystalline form of natural calcium carbonate, CaCO3, it is the main mineral composing most limestones and geological marbles. Also called calcspar
ETCHING Occurs when stone is eaten (or neutralized) by an acid. It often looks like and is mistaken for a watermark.
LIMESTONE Sedimentary rock originated mostly by the decomposition of marine organism composed primarily of calcite or dolomite. The varieties of limestone used as dimension stone are usually well consolidated and exhibit a minimum of graining or bedding direction
MARBLE A metamorphic crystalline rock composed predominantly of crystalline grains of calcite, dolomite, or serpentine, and capable of taking a polish
RESTORATION Work performed, including cleaning, repair, and finishing, returning the stone to its original character, finish, and condition
TRAVERTINE A variety of limestone that is a precipitate from hot springs. Some varieties of travertine take a polish and are known commercially as marble. ASTM C119-03 classifies travertine in both the limestone and the marble groupings
