Urine stains from pets or other sources can cause stains on your tile that traditional soap and water will not clean up. You can remove these stains by prepping the spot and then using a mixture of household ingredients to create a stain remover for the area. The removal of the stain will also remedy any lingering odours caused by the accident and the tile's prolonged exposure to the urine. The process can also be used on any other stains you find on your tile floors.
Add three to four drops of dish detergent to a damp washcloth. Work the detergent into a lather inside the cloth.
Wipe over the urine stain with the washcloth to remove any excess urine from the area. You can skip this step if you removed the urine after the initial accident.
Wipe the area with a dry washcloth to remove any excess water or soap.
Put on a pair of rubber dish gloves.
Stir 1 tsp of baking soda, 1 cup of vinegar and 1 drop of dish detergent in a large mixing bowl until the baking soda has completely dissolved. The vinegar and baking soda will react within the bowl causing a fizzing effect.
Pour the solution onto the stain using a measuring cup. Only pour enough to cover the stain and the immediate area. Let the solution set for 15 minutes.
Scrub the area with an old toothbrush or scrub brush. Wipe the area with a paper towel to check if the stain has been removed. Add more solution and repeat until the stain is gone.
Wash down the area with a damp paper towel and two drops of dish detergent.
Dry the area with a paper towel.
The baking soda will remove the odour from the urine. You can scrub the area with a solution of 1-part backing soda to 2 parts water if the odour remains.
