First, is the granite “sealed”? If yes, then here’s what you do:
Grab a 16-ounce (pint) empty spray bottle. Add 3 ounces of Eco Orange. Fill the rest with warm or even hot water. Spray on the area nice and good. Let it soak for a minute or two, and wipe. That should get the job done. As you already know, please don’t use a scrubbie pad or any abrasive on that beautiful granite.
