How can I remove Gorilla Glue smudges from a quartz countertop?
Using a "brand new" razor blade will remove the bulk of it. Scrape very gently against the dried glue at a sharp angle. Then use some #000 or #0000 steel wool to remove the remaining residue. Then wipe the area down well. I wouldn't suggest any harsh chemicals, it might dull the shine. Soap and water with a small amount of rubbing alcohol is about as far as I would go.
