Ways how to remove stains from Natural Stone.
Removing stains from marble, granite and other Natural Stones can be difficult. There are, however, several protective measures you can take: Any spill should be cleaned as soon as possible. Blot spills with a paper towel or clean whit rag. At this point, it is important only to blot, wiping a spill may spread it over a larger area, making a bigger mess. Use only cold water and stone soap or a neutral cleaner. Wash the area several times. If a stain is still present, a chemical poultice may have to be applied. Avoid using chemicals of any kind until you know which chemical cleaner to use. See Chemical Chart. Certain chemicals will react with the spilled material and could make the stain permanent. Natural Stones are porous materials, if not thoroughly sealed, they will stain. The only way a stain can be removed is to literally pull it out of the stone or ceramic with both a chemical and material that will absorb the stain. This chemical absorbent-material combination is what we call a Poultice. Poultices are usually powder or cloth materials that can be mixed with a chemical and placed on top of the stain. Clays and diatomaceous earth are safe and widely available, but do not use whiting or clays containing iron with an acidic chemical; iron will react with the acid, and may cause rust staining. It is best to purchase powders that are designed specifically for stone and tile. Consult a stone restoration specialist or your stone supplier (fabricator) if in doubt. Poultice materials you could use: Clean the stained area with water and stone soap. Remember to blot rather than wipe. |
