-Mop and towel dry with tentacle mop with a Neutral Ph cleaner dilluted per intructions. (No bleach, Vinegar, etc.)

-As you mop in front of you, keep a towel at your feet moving side-to-side picking up the excess water to keep from dirt build-up occurring. 

-Though the grout is sealed, it is still a valley that can harbor dirt if left untreated resulting in a dark grout line. 

-For deep cleaning, soak the line(s) for 10-15 minutes with a heavy concentration of cleaner and run the grout line with a soft, preferably microfiber cloth.

-It is highly recommended that a pre-mixed spray bottle of the Neutral Ph cleaner and a cloth be kept close by for spot cleaning.
