Sweep or vacuum floors to remove any dust or debris before using any cleaning products. Damp-mop your tile floor at least once each week (more frequently for heavy traffic areas) to decrease wear and abrasion from grit and soil.
TIPS FOR PREVENTING DAMAGE
Test scouring powders and sealants on a small area before cleaning the full area.
Use a sealer on grout joints shortly after installation and use products compatible with cleaning grout joints.
After cleaning, rinse the entire area with clear water to remove any cleaning solution residue.
Have any damaged or broken tile removed and replaced only by a qualified tile contractor.
