Marble stains removal- Stain Removal on Carpet and Upholsterys

Make a poultice from white absorbent material such as a napkin, blotter, paper towel or facial tissue, dampened with the chemical recommended to dissolve that stain; or mix whiting with that chemical to make a soft paste to cover the stain. The poultice should be left on the stain from 1 hour up to 48 hours, depending on the age and depth of the stain. Plastic wrap, held in place by masking tape, can be put over the poultice to keep it damp; otherwise it will have to be redampened with the chemical periodically. Mix only enough poultice for immediate use; mix a second batch if another application is needed.
