Many are intimidated by limestone because they think it is difficult to take care of. Quite the contrary – limestone is simple to take care of, but certainly requires specific care to keep it looking new and lasting for years. Cleaning your limestone is as easy as sweeping and mopping regularly.
-First, mop up any excess liquid immediately using a damp cloth.
-You can make what is known as a poultice, or mixture using flour and hydrogen peroxide. Simply make a paste using flour and adding hydrogen peroxide a little at a time until a paste forms. You can also buy premixed poultice at any home improvement store.
-Apply the paste and let it sit for 48 hours, or until it is hardened.
-Remove the paste with a soft edged scraper and wipe the floor with a damp cloth.
*REMEMBER: Only use the poultice on the limestone tile and white grout. Because peroxide is a bleaching agent, it can bleach colored grout!
If the stain is not removed, you may wish to replace the tile. It is helpful to purchase extra flooring materials at the time of installation to have matching limestone tiles and grout on hand.
