Most people think granite does not stain, they are wrong. All granite species are porous and their porosity varies from granite species to granite species. Food and beverage spills, especially greasy foods and cooking oil will stain the granite’s surface. Hair dyes, colored toiletries, paint and stain pigments, the colorants contained in chemicals, when spilled on granite, will seep into the granite’s pores and discolor the granite’s surface.

Be aware, and this is normal and typical for all granite countertops and granite islands in the kitchen, over time (usually in excess of one year), due to improper cleaning, not completely removing food and beverage spills, especially from greasy foods and cooking oil, plus the residue contained in smoke from cooking, attacks the granite’s color and clarity (the granite’s surface becomes much darker in color than when it was new).

We have finally developed a Granite Poultice, which removes deep embedded stains and discoloration from kitchen granite countertops and islands. Our Granite Poultice is specifically formulated to work below the granite’s surface and pull out grease and oil, plus food and beverages that have penetrated into the granite pores. Watch those dark, dull, and discolored areas of your kitchen granite countertops and islands disappear and come back to life. Your granite will look as beautiful as it did, on the day your granite was installed.

Granite Poultice is quick and easy to use; restoring the original color and clarity to granite countertops and islands usually takes 24 hours to accomplish, depending upon the age, depth, and severity of the granite’s discoloration and staining.

DIRECTIONS: mix the granite poultice with lacquer thinner to the consistency of cookie dough (lacquer thinner can be purchased at hardware and paint stores). Next, use a rubber, wood, silicone, or plastic spatula, to spread the granite poultice over the discolored/stained granite surface to a thickness ranging between 1/8 to ¼  inch (similar to a pancakes thickness). Next, cover the granite poultice with a plastic wrap or plastic sheeting applied to the granite surface with duct tape; making the granite poultice (airtight) allows the granite poultice to maximize its penetration into the granite pores and pull out grease and oil, plus food and beverages that have stained and discolored the granite surface. Keep the granite poultice in place for a minimum of 24 hours, to do its work; for extremely discolored/stained granite areas it may be necessary to keep the granite poultice in place for 2 or 3 additional days; and sometimes, a 2nd granite poultice application is necessary. Next, after removing and discarding the granite poultice, it is quite common for the granite countertop and island to appear darker than normal, this is because moisture from the granite poultice has not fully evaporated out of the granite’s pores; it usually takes a few days for the evaporation process, and the granite’s normal color, clarity, and gloss will be fully restored. After removing and discarding the granite poultice, use our granite cleanser NeutraClean For Granite to clean the restored granite area, then seal this granite area with our granite sealer Granite Guard Protector SB, then polish this granite area, with our granite polish Granite Polish and Protector . Our granite cleanser, granite sealer, and granite polish, are all included in our Granite Maintenance Kits along with additional items to clean, seal and protect your granite.
