Hi Thomas, Mix equal parts of white distilled vinegar and water, then pour the mixture onto the tile floor. Let it sit on the urine stain for up to 10 minutes. Use a clean sponge, mop or paper towels to mop up the water and vinegar, then rinse thoroughly with clean water.

My name is Linda. I'd use a combination of baking soda and vinegar. Sprinkle the baking soda on the stain (plus some water to make a paste if it's dry) and let it sit for a while. The baking soda will absorb the odor and will help with discoloration. Next spray with clear white vinegar mixed with a few drops of Dawn. Let that work then rinse with clear warm water. Repeat if necessary. Wishing you the best.
