Stone polish dried in grout

Q. I have a Limestone tile and someone let the polish dry in the grout. How can I remove the polish from the grout? The grout was not sealed. The product was granquartz stone polish.

A. Try applying a neutral cleaner to the grout where the polish has dried and agitating it with a soft bristle scrub brush. Remove the cleaner with a wet vac and repeat as needed. Once the polish is removed from the grout it would be a good idea to seal the grout to prevent staining and make clean up much easier in the future.
