How do I clean my floor tiles?

The steam may have affected the glazing or what ever was spilled. Especially if it's acidic.

Oh dear Sherry, sorry to hear that. You may find this tutorial helpful to get the gloss back - https://a1reglazing.com/blog/2018/06/15/restore-shine-ceramic-tile-restoration/ Best of luck

Sherry, if the spill included anything oily, your steamer won't cut it. Try mopping with hot water and a few drops of dish soap.

sounds like the smudge is oil based or the steam mop would have cleaned it up. Try some lemon essential oil - the citric acid in it may help break up the smudge so you can wipe it away.

I use this on my tile floors:

1 cup baking soda

1 cup white cleaning vinegar

1 Tbsp blue Dawn

2 gallons hot water (I boil about 1/3 of mine)
