Jon-Don’s new Matrix Grout Devil is “a powerful tile, grout and hard surface cleaner that cuts through layer after layer of soil buildup,” the company said.

Grout Devil is also an all-around tile and hard surface cleaner, as well as a pre-treatment additive that boosts the cleaning of other cleaning agents. It dilutes anywhere from 4 to 32 ounces per gallon, depending on the degree of soiling, and is not for use on furniture, glass or aluminum.
