If the urine was dry when you found it, you can still take measures to clean out the spot. First, create a cleaning solution. Combine in a small bowl 1⁄2 cup (120 mL) warm water,1⁄2 cup (120 mL) white vinegar, and 1⁄4 cup (59 mL) liquid dish soap. Mix it together until it creates a foam. Using an old toothbrush both stops you from having to buy a new scrubbing tool, and is soft enough so that the scrubbing won’t damage the upholstery.  This method involves scrubbing, rather than just dabbing or spraying, because the stain may be absorbed further into the upholstery as it has had time to dry and sit. Scrubbing enables the cleaning mixture to go deeper into the upholstery. You can use a rubber spatula to do this, or any other material that is hard and flat. This will effectively and quickly  wipe away any remaining foam. Get a cloth damp with water and use it to dab at the spot and remove any residue from the cleaning solution. Blot the area with a dry cloth until both the former stain and the cloth feel completely dry and stop picking up moisture.
