How to Clean a Juice or Wine Stain From Granite

I’m certainly not an expert when it comes to granite, but I can say from experience that a simple poultice of dishwashing soap and all-purpose flour will remove set-in stains like boozy cranberry punch.

During one of our annual Halloween bashes, we were serving up our floating eyeball punch (cranberry juice concentrate, a bottle of champagne, and a liter of lemon-lime soda) and we had just installed a new kitchen island with a granite countertop.

After the party, we discovered a set-in cranberry punch stain on our new granite!  It was a large circle the size of our punch bowl.  We were devastated.

Immediately, we did some research, and learned that there are several substances that can stain granite — like tomato juice, cranberry juice, and red wine.  Since granite is a pourous surface, it can be vulnerable to stains.  This is also why sealing is important.

To make a poultice, mix the dishwashing soap with flour to make a paste, spread the paste over the stain in a thin layer, cover with plastic wrap, and allow to dry or until the poultice is partially dry, but still moist enough to gently scrape it off the granite.  Then, wipe the area clean of any debris.

The poultice will leave a moist, darkened area on the granite until the area dries completely in a day or so, depending on the size of the stain.  We had to repeat the poultice process about three times over the course of a few days to remove our rather large stain.  Patience is key.

Visitors to our home would never know of our cranberry punch fiasco by looking at our island.  A poultice can be an affordable home solution to granite stains when store-bought cleaners prove ineffective.
