Yellow stains on marble tile.

Mold can stain marble bathroom countertops floors etc. Spread the baking soda paste in a thick layer on top of the stained marble tile. This process of oxidation is similar to the rusting of metal. This oxidation process is accelerated when the tile is saturated as in the flood in the above example.

The paste should be about 1 4 to 1 2 inch thick. These stains can be the result of a water glass that was left on a marble countertop for too long or from hard water buildup around sinks and showers. White marble tiles can remain for years without yellowing then over time may slowly turn yellow and in severe causes may turn completely brown. Iron stains however can be eliminated by mopping away water as accumulated in the marble tiles in order to prevent the iron from getting oxidized.

This process of oxidation is similar to the rusting of metal. Mold is a common problem in many bathroom settings. If water leaches into the core of the marble tile and contacts these deposits the iron will rust and bleed to the surface causing brown orange or yellow spots marble stains. This oxidation process is accelerated when the tile is saturated as in the flood in the above example.
