When people in your house walk across the floor, they occasionally leave black scuff marks behind. These unsightly marks can be hard to remove, and often do not come off during your regular floor-cleaning routine. There are, however, a few quick ways to get rid of scuff marks without causing any damage to your flooring.
Scrub the black scuff mark with a damp cleaning rag, which often removes much of the residue.
Sprinkle a thick coat of baking soda over the scuff mark, which creates a gritty texture that is safe for the porcelain.
Pour an even mixture of water and white vinegar into a spray bottle, and mist it heavily over the baking soda to dampen the baking soda.
Scrub with the mixture and a damp cleaning rag.
Rinse the rag with plain water, and wipe your porcelain tile to get rid of any leftover cleaning residue.
