In this case study, Bob Deweese describes how one of his Rite Rug techs made an unusual discovery on what seemed to be an everyday grout cleaning job. The grout being cleaning was actually a few shades darker than it appeared. What had lightened the grout? A coating of salt formed during a process called efflorescence.
