Deep urine stains and odors require breaking down uric acid crystals, which standard soaps cannot do. First, neutralize the stain with an enzymatic cleaner. Next, oxidize any remaining pigment using an oxygen-based bleach or a DIY peroxide mixture, blotting the area until completely dry.
To remove dried urine stains, first lightly rehydrate the area with water, then apply an enzymatic cleaner to break down the uric acid crystals. For tougher stains, follow up with a 3% hydrogen peroxide solution to oxidize the mark, blot thoroughly, and let it air dry completely.
Old urine stains
Once you find the stains, it's important to note that they'll require more stain remover than fresh stains. “Instead of using a simple enzyme cleaner, you may want to try an oxygen-activated enzyme cleaner to remove the stains and destroy the odor.

Old or dried urine stains can be difficult to remove, often leaving carpet fibers permanently discolored or with an unpleasant lingering odor. The odor of old urine is due to the bacterial decomposition of the urea in the urine which continues as long as there is moisture.
To remove calcified urine (urine scale), you need to use an acidic cleaner, which breaks down the mineral deposits so they can be easily scrubbed and washed away. The most effective approach is to apply a targeted acid, let it soak, and gently scrub the surface.

Dawn dish soap has a million uses, including removing urine stains and odor from carpets. When combined with hydrogen peroxide, this disinfectant mixture will break down stains on a molecular level and kill bacteria, making it one of the best pet stain removers.
The longer you allow it to sit on a carpet, the deeper it engrains into the fibres of the carpet. This makes it increasingly difficult to remove. The ammonia that ends up growing in the urine can result in colour changes. This is even more true if there are any blue tones in the flooring.
Permanent Damage: Some urine spots may be immediately noticeable, while others may take weeks or months for a reaction so the dyes and carpet fibres may be permanently damaged. In beige carpets, blue dyes are attacked, leaving behind the red and yellow dyes with a resulting stain appearing red, yellow, or orange.
How to Get Old Stains Out of Clothes
Brown or tea-colored urine is often caused by dehydration, certain medications, or dietary changes. However, it can also signal blood in the urine or an underlying liver or kidney issue.
Yes, hydrogen peroxide helps break down the organic compounds in urine, specifically eliminating yellow stains and destroying odor-causing bacteria through oxidation. It is highly effective for immediate spot treatment on hard floors, woven fabrics, and artificial turf.
Leaving urine in the toilet accelerates the buildup of stubborn "urine scale". While standard limescale comes strictly from minerals in your tap water, urine contains calcium, magnesium, and proteins.

To confirm if a stain is pee, use a UV blacklight in a dark room. Urine contains phosphorus, which causes it to glow a dull yellow or pea-soup green under UV light. Other clues include a distinct ammonia smell and localized dye fading.
