Regular cleaning is recommended, but the frequency depends on the usage in the area. For most installations and applications, the use of an appropriate cleaner, such as MAPEI's UltraCare Concentrated Tile & Grout Cleaner for floors, or UltraCare Everyday Stone, Tile & Grout Cleaner; UltraCare Everyday Stone Clean & Polish; and UltraCare Everyday Stone & Grout Cleaner & Resealer for countertops and backsplashes, is recommended routine maintenance.
