Well, the provided search results were about as helpful as a screen door on a submarine, offering nothing but a website menu and a link to a Reddit thread. But don't you worry, your leather sofa's dignity can still be salvaged from this olfactory offense.
So, the unspeakable has happened. Your majestic leather throne has been christened by a pet, a small child, or perhaps a guest who really over-celebrated. The key is to act fast, before the evidence seeps deep into the cushions and becomes a permanent resident. First, blot the area immediately with a clean, dry cloth or paper towels. Press firmly to soak up as much of the liquid as you can. Whatever you do, don't rub! Rubbing just grinds the problem deeper into the leather's pores.
Next, it's time to play kitchen chemist. Mix a solution of equal parts white vinegar and water. Vinegar is a champ at neutralizing the ammonia in urine. But hold on—before you go dousing your prized possession, test your potion on a small, hidden spot to ensure it doesn't discolor the leather. If all is well, dampen a clean cloth with the solution and gently wipe the affected area. Don't saturate it; we're cleaning, not marinating. Follow up by wiping with a cloth dampened with just water, then dry the spot thoroughly with a clean towel.
If a phantom smell lingers after the spot is completely dry, it's time for the big guns: an enzymatic cleaner. These magical concoctions contain enzymes that literally break down and consume the uric acid crystals that cause the lingering odor. It's science, but it feels like sorcery. Make absolutely sure you get a cleaner that is specifically formulated and safe for use on leather. Follow the product's instructions to the letter. After the cleaning ordeal is over and your sofa is dry, treat it to a good leather conditioner to restore its moisture and keep it from becoming sad and cracked. Your sofa will thank you for the spa day after its traumatic experience.
