Tile Floor Cleaning Basics
You can sweep/vacuum your tile floors to keep them clean. Tiles maybe prone to dirt, but grit and dust can dull the surface. You can clean the tile with mild detergent and clean water, using a rag or mop . It pushes dirty water into grout lines and it makes harder to clean. Change the water frequently because a dirty water makes the your floor cloudy.
Get Rid of Residue
Soap residues makes your floor look blurry. Using a mild all-purpose cleaner and fresh lemon juice can remove the residue on ceramic tiles but never try it on marble. Rinse it with a clean water and wipe with a dry fiber-free cloth. You can use your foot to slide the cloth over the floor, it can also be a good exercise for your feet.
Grout is permeable and can easily imbibe grease and other stains. Baking soda and water are the real secret for a clean-cut grout. Make a paste of baking soda and water, rub it on the stained grout, leave it overnight and in the morning scrub the stained grout with a nylon cleaning brush not a metal brush cause it can damage the floor. Repeat it until the stain is gone. To prevent future stains apply a silicon-base sealer to the grout.
