HydraMaster introduces Q.C.T., a quarry and ceramic tile cleaner. Composed of special surfactants and D-Limonene, Q.C.T. is designed to penetrate and emulsify dirt and grease build-up in tile pores and crevices.

The new formula uses hydrogen peroxide with a pH of 3, allowing the ability to clean grout without attacking or de-mineralizing it, according to HydraMaster. Q.C.T. whitens grout lines without leaving residue, and is safe on marble, slate, natural stone, terrazzo and concrete, the company says.
