FIRST, don’t overwork your surface with a misguided, over-marketed cleaner who’s over the top marketing campaign focuses only on the quick buck rather than sure-fire solution.  SECOND, recognize and fix the damage that already exists.

Do you know the first thing a professional tile restorer will do to eliminate stained grout?  Apply a mild acid. This is done in order to REMOVE the seal before applying a new seal.  This makes sense ONLY if you are planning on applying the new seal, then subsequently an ideally non-acidic sensitive seal.  As you can see, use of an acidic cleaner on a grout floor cannot be a good idea.  Sure it provides a lighter stain, giving the appearance of being cleaner, but one has just opened the floor to actually accepting stains more easily.  Oops! And it gets worse! Because clearly the marketer wants you to use more of their cleaner.

If this sounds like your situation.  Relax.  We’ve got you covered.  First, let go of that acidic cleaner.  Back away from the bottle.  Take a breather.  Now let’s get this fixed!  First, halt the damage.  Shift to MARBLELIE TILE & GROUT Cleaner, or if you have marble MARBLELIFE Marble & Travertine Cleaner.   These products will remove the grease and oil and clean your tile without doing any damage.
