While the provided links confirm this is a very common and frustrating problem, they do not contain specific cleaning instructions. Drawing on expert knowledge, here is the most reliable and effective way to handle a pee accident on your sofa and ensure it's truly clean and odor-free.
Don't panic! The absolute key to success is to act quickly. Before you reach for any cleaners, grab a stack of paper towels or a clean, thick cloth and blot the wet spot firmly. It is essential that you blot, not rub or scrub. Your goal is to press down and absorb as much of the urine as possible to stop it from soaking deeper into the cushion. This single step will make the rest of the process far more effective and is the most important thing you can do in the first few minutes.
Once you have blotted the area until it is just damp, you can create a simple but powerful cleaning solution. In a spray bottle, mix equal parts of cool water and white vinegar. Vinegar is a fantastic natural cleaner that works to neutralize the uric acid in the urine, which is the component that causes that stubborn, lingering smell. Lightly spray the affected area—you don't want to saturate it, just dampen it—and let the solution sit for about 10 to 15 minutes. After it has had time to work, use a new, clean cloth to blot the area again, lifting the vinegar solution and the broken-down urine out of the fabric.
Finally, to guarantee no smell remains, turn to baking soda. While the spot is still slightly damp from the cleaning solution, sprinkle a generous layer of baking soda over the entire area. Baking soda is a miracle worker for absorbing leftover moisture and trapping bad odors. Let it sit for at least four hours, but leaving it overnight is even better. Once it's completely dry, use your vacuum's hose attachment to thoroughly suck up all the baking soda. You will be left with a sofa that is not only clean but completely fresh, with no trace of the accident left behind.
