How to Remove Green Food Coloring from Granite or Quartz

St. Patrick’s Day is just around the corner and many of us love to cook up a green treat or two for our families to bring some festive fun to the day. What is not so fun is spilling some of that green food coloring you used in the pancake batter on your beautiful granite counter tops. Even if they are recently sealed the stain can be hard to remove.  How to Remove Green Food Coloring from Granite or Quartz

Don’t panic, there is a way to remove that green dye from your counters. You will need to mix up a poultice. Follow these simple instructions to get your granite counters looking beautiful again.  



  • Paper towels 
  • Talcum powder 
  • Plastic container 
  • Acetone 
  • Plastic Wrap 
  • Masking Tape 
  • Plastic Spatula 



  1. Begin by blotting the stain as soon as possible ( immediately after it happens if possible) with a clean white paper towel to get up all of the excesses. Soak up the spill working from the outside toward the center to avoid spreading.  
  2. Next, make your poultice by taking a few teaspoons of talcum powder mixed with a few drops of acetone in the plastic container. You want to make a paste that is similar in consistency to peanut butter.  
  3. Spread the freshly made powder poultice generously over the stained area and about a half an inch past the outer edges of the stain.   
  4. Let the poultice sit and lay a sheet of plastic wrap over the area.  
  5. Tape the edges of the plastic wrap to the counter with your duct tape to provide an air tight seal so that the reactant (acetone) does not evaporate and cause the poultice to dry out.  
  6. Let the poultice do its work on the stain for about 48 hours. 
  7. After the first 48 hours is up, carefully remove the tape and plastic wrap from the counter and allow the poultice to air dry.  
  8. Once the poultice is dry, scrape the poultice very gently and carefully from the counter with the plastic spatula.  
  9. When you have scraped as much of the poultice away as you can, follow it with a rinse of plain water. The stain should be gone, but if some remains repeat the process over again with new freshly made poultice.  


Alternative Methods:  

  • You can use other materials to make a poultice. You can mix one of the following absorbents: diatomaceous earth, baking powder, powdered sugar, flour, or molding plaster—with one of the following reactants: water, 12 percent hydrogen peroxide, ammonia, hand dishwashing soap, or bleach. *Note: you do not want to use an abrasive powder or an acidic reactant these can eat through the sealant and permanently damage your granite. Also never use more than one reactant especially bleach and ammonia—these two substances emit harmful fumes when mixed.  
  • Instead of using a powder and mixing a poultice you can soak several cotton balls, or paper towels in one of the reactant liquids and lay them on the stain then cover with plastic wrap and tape.  


Tip: Natural stone sealants are so important to help aid in the clean-up of stains, spills, and daily dirt before they absorb into the stone. You can tell if your stone needs to be sealed by placing a small amount of water on the counter. If the water beads up the sealant is in great shape, if the water absorbs into the counter it is time to re-seal.
