Using a clean, dry towel or a paper towel, gently blot the affected area to soak up the pee. Do not scrub this area since it may make the urine seep deeper into the mattress layers. Instead, gently blot the spot. Removing urine from a memory foam mattress will be difficult if you let it seep deep into the layers.

Alternatively, after removing other bedding, you can spray the affected area with pee-busting spray. Lay clean, dry towels on top of this area, followed by a layer of newspapers, then stack a heap of books on top of the newspapers. While the spray help neutralizes the urine smell, the towel helps wick away as much liquid as possible. On the other hand, the newspaper helps shield the books from urine.

Also, remember to turn on the fan or open the room's windows to allow for efficient airflow. Continue bloating the affected spot until they dry or paper towels aren't picking up any liquid. Alternatively, you can sprinkle baking soda on the affected area to absorb the remaining moisture.

When dealing with dog or cat pee, leave the baking soda layer on the affected spot until its white hue darkens. This shows that the baking soda is absorbing the urine. Vacuum-clean the baking soda, then repeat the process with fresh baking soda until it stays white to ensure it has absorbed all the urine.

Using pure vinegar solution is also okay, as it won't damage your mattress.

If discoloration is a significant concern for you, you can use distilled white vinegar on the affected spot. Also, remember to use this mixture within an hour or two because hydrogen peroxide breaks down faster. Otherwise, you'll need to prepare a new mixture.

The same way you use baking soda to remove stains is the same way it's a perfect deodorizer for pee odor. Remember to add more baking soda to the affected spots, especially the strong-smelling ones.

Afterward, apply baking soda and let it sit for a couple of hours before vacuuming it. Advisably, you should place the mattress under direct sunlight for a few hours to ensure it dries completely. This helps eliminate any lingering odors. Not to forget, this whole process also helps remove dry pee stains.
