The most effective way to remove odor from leather car seats is a multi-step process: identify the source, thoroughly clean with a pH-balanced leather cleaner, and condition the leather to restore its natural protective barrier. For persistent smells, a baking soda treatment or using a leather-safe odor eliminator is necessary. The key is to avoid harsh chemicals like ammonia or vinegar, which can permanently damage the leather's finish.
Start by vacuuming the seats to remove loose debris. Then, use a dedicated pH-balanced leather cleaner (a measure of acidity/alkalinity that is gentle on leather) with a soft microfiber cloth. Work in small sections, wiping away grime and body oils that trap odors. After cleaning, a crucial step is applying a quality leather conditioner. This replenishes the leather's natural oils, preventing it from drying out and cracking, which can harbor smells.
For stubborn odors, sprinkle baking soda generously over the dry seats, let it sit for several hours or overnight, and then vacuum it up completely. As a final measure, a product like a leather odor neutralizer uses enzymes to break down odor molecules at the source. Regular maintenance is the best prevention.

My go-to method is quick and uses stuff from the pantry. First, wipe the seats with a damp cloth. Then, mix a 50/50 solution of distilled water and white vinegar. Lightly mist it on, wipe immediately, and let it air dry completely—the vinegar smell disappears as it dries. Follow up with a leather conditioner. This works great for food or mild smoke smells. Just test the vinegar mix on a hidden spot first.

As someone who details cars, I focus on the cause. Odors sink into dirty leather. You need a proper leather cleaner to lift the oils and grime out. Conditioning afterward is non-negotiable; it seals the leather so smells can't penetrate as easily. For a deep-seated problem, a steamer can work wonders by lifting impurities from within the leather pores. Always, always do a patch test with any new product.
