How do i clean floor tiles with hardened cement droppings?

Try apply white vinegar to the cement and allow to sit on for about an hour.The acidity should losen the cement.

To add to Janet's response. For mild problems such as small spots or a thin film of cement, white vinegar typically provides enough acidic power to loosen the bond between the cement and the tile. Use a sponge or pad to apply enough vinegar to the area to cover it completely. Allow the vinegar to set on the cement for at least an hour or two. If the weather is warm and the vinegar is evaporating, reapply frequently to keep the area moist. After the cement starts to loosen, scrub the area with either a brush, Scotch Brite pad or scouring pad. It will take some elbow grease, but the vinegar will have loosened the cement enough that it can be scrubbed away. If a small amount remains, reapply vinegar and allow it to set again. Scrub again until all of the cement is removed. Rinse the area with water. Wash the area with soap and water. Rinse the area again to ensure all of the acid is removed.
