How can I properly maintain and clean the tiling and grout in my bathroom to ensure they stay in good condition?

To properly maintain and clean the tiling and grout in your bathroom, regularly sweep or vacuum to remove dirt and debris, then mop with a mild detergent or a mixture of water and vinegar. For tougher stains, use a grout cleaner or a paste of baking soda and water. Seal the grout annually to prevent moisture and mold buildup.
