Most stains can be removed by some simple cleaners and a gently hand. For tougher stains, a little more love and care is required. Learn how to tackle a tough stain by using a poultice.

What is a Poultice?

A poultice is a liquid cleaner or chemical mixed with a white absorbent material to form a paste that absorbs the stain out of the stone.

Making a Poultice

Poultice materials include kaolin, fuller’s earth, whiting, diatomaceous earth, powdered chalk, while molding plaster or talc. Roughly one pound of prepared poultice material will cover about one square foot of stone. Do not use whiting or iron-type clays such as fuller’s earth with acid chemicals. The chemical reaction will cancel the effect of the poultice. Cotton balls, white paper, and gauze pads can also be used when preparing a poultice.  Premixed poultices are also available at stone maintenance supply companies.

Applying a Poultice to the Stain

  1. Prepare the poultice. If using a powder, mix the cleaning agent or chemical to a thick paste, about the consistency of peanut butter. If using paper, soak it in the chemical and let drain. Don’t let the liquid drip.
  2. Prepare the stained area by wetting the stained area with distilled, clean water.
  3. Apply the poultice to the stained area about ¼” to ½” thick. Extend the poultice beyond the stained area by approximately one inch. Use a wood, plastic spatula, or a scraper to spread the poultice evenly.
  4. Cover the poultice with plastic. Tape the edges of the plastic to the stone to seal it down.
  5. Allow the poultice to dry thoroughly. This step usually takes about 24-48 hours. Known as the drying process, this is what pulls the stain out of the stone and into the poultice material. After the 24-48 hours, remove the plastic and allow the poultice to dry.
  6. Remove the poultice and rinse with distilled water. With a soft cloth, buff the area dry. Use the wood or plastic scraper if necessary.
  7. Repeat the poultice application if the stain is not removed. It could take up to five or more applications for difficult stains.
  8. If the surface is etched by the chemical, apply polishing powder and buff with a polishing pad.

There is a possibility that some stains may never be completely removed. Consult with a professional to determine if any additional steps need to be taken.
