Some white absorbent material can be white cotton balls, paper towels, cleaning cloths, or even baking soda. White flour may also be used. The liquid solvent will vary depending on the type of stain you’re removing. The stain will first need to be identified. Afterward you can then use the best and proper stain removing method.

Identifying Stains on Marble

Rust Stains – Rust stains are easily identified, with an obvious copper or brownish color and often in the shape of a metallic item. Rust stains are most common in bathrooms or on countertops or areas with high moisture exposure. Unfortunately, rust is also one of the most difficult types of stain to remove from marble. The best solvent for a rust stain is a commercial liquid rust stain remover.
Organic Stains – Organic based stains are stains that may have occurred from foods, and liquids or even hand soaps, lotions and plant matter. Organic stains may vary in color depending on the source. However the color will be similar to the source of the stain. The best solvent for organic stains is 6% hydrogen peroxide.
Oil Based Stains – Oil based stains become very dark in color. In many cases food, drinks, or other solvents high in oil will leave behind a pinkish-brown or dark brown color. The best solvent for oil based stains is acetone or mineral spirits.
Ink Stains – Ink stains from pens, markers and even red wines. Ink stains will leave behind the pigment of the ink onto the marble. Ink stains are easily identified. The best solvent for inks is 6% hydrogen peroxide or ammonia.

Making a Marble Poultice

The first step to making your own poultice is to get a bowl and add one cup of the recommended solvent for the stain you’re removing. Then combine baking soda with the solvent until it forms a paste similar to the consistency of peanut butter. Before applying the mixture, wipe the area clean with a clean cloth. Use the mineral water to dampen the cloth. The mineral water that is poured onto the marble allows the cleaning mixture to penetrate deeper. Next, apply the mixture. Since it is a paste, make sure to cover the stain with the paste about ¼ to ½ of an inch in height. Make sure there are no air pockets in the paste. Cover the paste with plastic wrap and use the masking tape to hold down the edges so it seals the paste in. Keep the paste on top of the stain until the paste completely dries and hardens. This may take 48 hours. To remove the paste, pour water over the top of the poultice to soften it and then use a wooden or plastic spatula to scrape the paste off of the marble. Next wipe the surface clean with plain water.
