To clean, maintain, and upkeep tiles effectively, sweep or vacuum regularly to remove dirt and debris, then mop with a mixture of warm water and a mild tile cleaner or vinegar solution to remove stains and grime. Avoid harsh chemicals that can damage the grout or tile surface. For grout, use a soft brush and a baking soda and water paste or a specialized grout cleaner to keep it clean and prevent mold. Seal the grout every 6 to 12 months to protect against stains and moisture. Promptly wipe up spills to prevent staining, and avoid abrasive tools that can scratch tiles. Regularly inspecting tiles for damage and repairing any cracks or chips will prolong their lifespan and maintain their appearance.
