Tomato Stain
TOMATO SAUCE

Types:
Barbecue, steak, spaghetti and catsup.

Problem:
These sauces contain tomato, tannin, oil and dyes. The dyes will leave a red to brown stain. The oil will penetrate the stone and darken.

Solution:

1.Clean area thoroughly with cold water and a good detergent (Ivory works well).

2. If stain is still present clean the area with an alkaline degreaser (Commercial degreasers are available at most janitorial supply houses).Mix with water according to directions and let solution stand on stained area for several minutes. Agitate with a cloth and rinse with clean water.

3. If stain is still not removed than poultice with powder (diatomaceous earth or similar powder) and an alkaline degreaser. A second poultice may be required using powder and a solvent such as Toluene or Methylene chloride if there is dye present.
