Why Dried Dog Urine Is Tricky
When urine dries, it leaves behind uric acid crystals. These crystals are what cause the lingering smell, and they can be reactivated by moisture. That's why simply wiping the area isn't enough. You need a cleaner that breaks down the uric acid, not just masks the odor.
Cotton is a natural fiber that absorbs liquids readily, making it especially prone to deep-set stains and odors. It's also a durable fabric, but it can be damaged by harsh chemicals or vigorous scrubbing.
What to Do First
If you've just discovered the dried spot, don't panic. The first step is to remove any solid debris with a dry paper towel or a vacuum cleaner with an upholstery attachment. Do not rub or scrub, as this can push the urine deeper into the fibers.
Next, test any cleaning solution on a hidden area of the couch, like the back or under a cushion, to make sure it doesn't cause discoloration or damage.
