Things You'll Need
Cat urine retains an obvious, offensive smell that you do not want persisting in your home. Cleansing it from your tile is crucial for a cozy, odor-free home; to safeguard the tile from inevitable staining; and to help protect visitors who may have allergies. If your cat detects the odor of urine on your tile, it may urinate on the same spot again in an attempt to "mark" the same spot. Proper cleaning helps prevent recurrences while you train your cat properly. One of the best ways to remove odor without damaging your tiles is to use baking soda.
Mix one cup baking soda with water. Add the water slowly while using a wooden spoon to mix it with the soda until you have a thick paste.

Paste the baking soda onto the tiles with urine odor using a spatula. Scrub the baking soda into the tile with a scrub brush and let it sit for 30 minutes.
Rinse the area with water until you remove all traces of baking soda. Mop the area with floor detergent and water when done.
To help eliminate staining and lingering odor from cat urine, you should clean up after accidents immediately. The longer urine has to soak into the tiles, the harder it is to get the smell out. If the cat odor returns after using baking soda, apply the baking soda again and the seal the entire floor with a tile floor sealer to prevent the odor from coming back to the surface. If you are unsure where the odor is coming from, use a black light to locate the stains. Cat urine always leaves behind a stain that shows up when exposed to a black light. For best results, turn all the lights off in the room and close the curtains.
Another recommended option for removing cat urine is vinegar. While effective, vinegar can also eat away at and damage tile. Baking soda is a safer choice for tile. If you want to use white vinegar instead, test it on a small area of tile first.
