I Tried 4 Grout Cleaners, and This Is the Only One I'll Buy

Although I do like the look, feel, and durability of the porcelain tile in our kitchen, bathrooms, and sunroom (I never had it before living in Florida), if I had my druthers, I would say goodbye to grout in my life. Especially the grout on the floor that it seems we're constantly bathing in some manner of liquid dirt--from tomato sauce splatters to murky mop water.
