How to clean porcelain tiles
Sweep the floor with a dust mop.
Start by sweeping the floor to remove any dust on the porcelain tiles. You can use a dry dust mop or a vacuum.
You can also use a microfiber mop, as it will be gentle on the tiles. Brooms with straw or plastic bristles will be too harsh on the floor and could scratch the tiles.
