How can I remove pet urine odors from tile floors?

Go to your local pet supply store, they carry lots of products for that. We use Nature's Miracle on our rugs, not sure if it's good for tile, but they would know best. Good luck.

Once you get your tile clean be sure to seal to protect for next time.

You can rent a steamer machine and try to clean them with that.
