Cement Grout Residue Remover for Polished Stone Directions

To Remove Cement Grout Residue

First pour the solution directly on the tiles and spread with a White Scrub Pad (FC210) and scrub the surface gently avoiding the grout joints as much as possible. Then allow it to work for 5 minutes or until the grout residue has been lifted.  Next rinse thoroughly with 1 part Heavy Duty Cleaner (FC350) to 3 parts water. Rinse again with clear water.

To Remove Cement Grout Joints

First, remove any sealer on grout joints with appropriate FCS Solutions Ltd. Remover. Then apply the solution at full strength directly on the joints. Allow it to work for 15 minutes or more before scraping the surface with a joint scraper. Repeat as needed. When the joints are clear of grout, rinse thoroughly with 1 part Heavy Duty Cleaner (FC350) to 3 parts water. Clear the joints of any residue, preferably with a wet vacuum and wait until the joints are completely dry before applying new grout.
