Say goodbye to dirty tile and grout! GranQuartz 631C Heavy Duty Porcelain, Ceramic, & Grout Cleaner is a high intensity, restoration-grade cleaner for use on porcelain and unglazed ceramic tile and is excellent as a grout cleaner. 631C provides industrial / institutional grade cleaning power that makes short work of oily, greasy, embedded dirt on tile surfaces and grout lines. GranQuartz 631C is highly effective in removing embedded soiling from porcelain tiles with dirt retention problems.
Unlike conventional acid-based tile and grout cleaners, 631C will not change or fade colored grout, and will not damage even the most sensitive porcelain surfaces when used as directed.
GranQuartz 631C provides the professional-grade power you need for tile and grout restorative cleaning, post-construction clean up, the removal of wax coatings, to clean oil and grease spills, and to restore tiles that have darkened with time due to ground in dirt and grime.
Porcelain tiles and grout lines that experience dirt retention problems should be sealed (impregnated) with GranQuartz 433P Porcelain Floor Impregnator.
