Excuse me, how to deal with the yellow stain on marble?

Professional marble cleaning agent can be used for cleaning, which can penetrate into the micropores of carbonate stones such as marble, limestone, dolomite, serpentine, etc., and remove various yellow spots and stains such as brown, brown, straw rope yellow, etc., without damaging the surface luster of the stone and leaving pigments inside the stone.

The correct washing steps are:

1. Remove the dust and dirt on the stone surface first;

2. Brush or spray the diluted cleaning agent on the surface of spots and stains, stick it on the stone surface with absorbent materials such as white cotton cloth or white toilet paper, and add the cleaning agent to make it completely soaked;

3. Cover the marble with plastic film to keep the action time of the cleaning agent;

4. After about 24 hours, remove the plastic film and the attached cloth or paper, and scrub it with clear water for several times;

If the yellow stain can't be completely removed, you can do it again according to the above method.
