15. Clean the grout with toilet bowl cleaner
Stained grout makes entire floors appear dirty and neglected. For thorough cleaning, apply toilet bowl cleaner directly onto grout lines and allow it to work for approximately 15 minutes. Scrub vigorously with an old toothbrush, rinse completely, and dry the surface. The powerful cleaning agents remove stubborn stains and restore the grout's original bright appearance, making your floors look newly installed.
