The answer to 'best way to clean tile and grout cleaning' is to use a combination of elbow grease, the right cleaning products, and proper techniques. Start by sweeping or vacuuming the tile to remove any loose dirt or debris. Then, mix a solution of warm water and a mild, pH-neutral tile cleaner. Apply the solution to the tile and grout using a scrub brush or sponge, and let it sit for a few minutes to allow the cleaning agents to work. Scrub the tile and grout in a circular motion, paying extra attention to any heavily soiled areas. Rinse the area thoroughly with clean water and dry it with a clean, dry towel.
For tougher stains or discolored grout, you may need to use a grout brush or a tile and grout cleaner specifically designed for deep cleaning. Always test any cleaning products in an inconspicuous area first to ensure they don't damage the tile or grout. If the grout is still looking dull or discolored after cleaning, you can try sealing it to protect it from future stains and discoloration.
