The Good Stuff
Good Stuff is a scientifically blended formula, hard surface cleaner that removes mildew, mold, algae, oil scum, oxidation, rust, brine, soap build-up, hard water deposits, stains, minerals, grease, body oils, caked on deposits and other discolorations on all types of glazed and unglazed ceramic tile and grouting. Unique brightening agents and color enhancers help bring back the luster. The specially formulated silanes not only help restore the shine to the finish, they also form an invisible protective barrier which can help stop recontamination of the restored area as well as making future cleaning simple.
