Most people think granite will never stain. They are wrong. All granite species are porous and their porosity varies from granite species to species. Food and beverage spills, especially that of greasy foods and cooking oils, can stain a granite surface over time. 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 surface.
It’s important to be aware that this is normal and typical for all granite countertops and granite islands in the kitchen. Over time (usually in excess of one year), improper cleaning (such as not completely removing food and beverage spills or residue contained in smoke from cooking) attacks the granite’s color and clarity. As a result, the granite’s surface becomes much darker in color compared than when it was new.
The Solution to Remove Stains from Granite
We have finally developed a Granite Poultice, which removes deeply 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. The product usually takes about 24 hours to fully remove stains from granite, depending upon the age, depth, and severity of the granite’s discoloration and staining.
How to Use Granite Poultice Remove Stains & Discoloration
Our Granite Poultice is highly effective at removing stains from granite. Follow these do-it-yourself instructions below.
- First, mix the granite poultice with lacquer thinner to the consistency of cookie dough (lacquer thinner can be found at hardware and paint stores).
- Next, use a rubber, wood, silicone, or plastic spatula, to spread the granite poultice over the discolored or stained granite surface to a thickness ranging between 1/8 to ¼ inch (similar to a pancakes thickness).
- Tightly cover the granite poultice with plastic wrap, or use plastic sheeting applied to the granite surface with duct tape. The idea is to make the granite poultice airtight, enabling granite poultice to maximize its penetration into the granite pores and pull out grease and oil that’s stained the granite surface.
- Keep the granite poultice in place for a minimum of 24 hours in order to get the best results. For extremely discolored or stained granite areas, it may be necessary to keep the granite poultice in place for two or three additional days. (In some cases of deeply stained granite, a second application of granite poultice is necessary.)
- Next, after removing and discarding the granite poultice, it is quite common for granite countertops and islands 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 cleaner 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.
Our Granite Poultice is very economical and easy to use. Use one pound of granite poultice to restore two square feet of granite. You can learn more about this product by clicking here.
