Remove Gum Stain from Polished Concrete
If you have stains on your polished concrete countertop or floor, there are a few different approaches for removal. You can still freeze it off with an ice cube wrapped in a plastic bag. However, it’s imperative that you scrape it off as gently as possible; do not risk scratching the polished surface.
To remove the leftover stain, use a mixture of liquid laundry detergent with warm water and soap, which are safe to use in non-porous and porous forms of concrete. All it takes is about two tablespoons of liquid laundry or dishwashing detergent mixed with regular soap and water in a medium sized container. Submerge a clean cloth in the solution and gently scrub the gum stains off the countertop or concrete floor. Repeat the process until the stain is fully gone.
Use concrete specific cleaning products or PH balanced wipes to keep concrete clean. Always be on the lookout for chewing gum and get rid of it immediately before it begins to penetrate through the concrete surface. Fresh gum is a lot easier to deal with.
