This silver sulphide tarnish can be quite easily removed using polishes that contain abrasives to rub off the silver sulphide, but these have the disadvantage of also removing small amounts of silver. Handily, chemistry provides a method which sidesteps this problem.
Remove stains from your travertine floors. As a porous stone, travertine stains easily. After identifying what caused the stain, use specific products to remove the blemish. Oil-based stains darken the stone and must be removed with chemicals. Blot the stain with a clean cloth to remove any excess residue. To remove the stain, use a soft liquid household cleaner, such as ammonia, acetone, or detergent. Apply the product to the stone on a damp cloth. Place the cloth over the stain to draw out the oil-based product.
