Heavy Duty Cleaner FC350 Directions

Wax and water-based finish and sealer removal: Mix 1L of cleaner with 2L of warm water. Increase concentration if needed. To remove a urethane water-based sealer, use straight concentrate. With an FCS Mop (FC230) and the Cleaning Mop Cloth (FC235) spread generously and then allow it to work for 5 to 10 minutes while scrubbing with an FCS black Scrub Pad (FC205). Work in small sections to never allow the solution to dry on surface. For large areas, use low-speed buffing machine with a black scrub pad. Remove stripping solution, if possible, using a wet vacuum. Rinse thoroughly with warm clear water. Allow to dry for 24 hours before applying a sealer or an acrylic floor finish.

Deep Cleaning: Pour the cleaner straight from the bottle on the surface and spread with an FCS Green Scrub Pad (FC215), White Scrub Pad (FC210) or Black Scrub Pad (FC205) or a nylon brush. Then allow the solution work for 3 to 5 minutes. Work in small sections to never allow the stripping solution to dry on the surface. Add an equivalent amount of warm to hot water on the surface and scrub. Let the solution work for another 3 to 5 minutes while scrubbing. Remove the solution with a mop or preferably a wet vacuum, rinse thoroughly with warm clear water and pick up.
