The answer to 'how to clean tile' is to use a combination of mild detergent, warm water, and a soft-bristle brush or sponge. Start by sweeping or vacuuming the tile to remove any loose dirt or debris. Then, mix a small amount of mild dish soap or all-purpose cleaner with warm water in a bucket. Dip your brush or sponge into the solution and gently scrub the tile, paying extra attention to any grout lines or stubborn stains. Rinse the tile with clean water and dry with a clean, soft cloth.
For tougher stains or built-up grime, you may need to use a tile-specific cleaner or a diluted bleach solution. Be sure to test any cleaning products in an inconspicuous area first to ensure they don't damage the tile or grout. If the tile is still not coming clean, it may be time to call in a professional tile cleaning service.
