Eliminate urine odor from mattresses, clothing, and upholstery with simple science-backed cleaning steps—plus prevention tips from Underx.
The sharp, sour scent of urine is one of the hardest household odors to forget—and even harder to remove. Whether it’s from a pet accident, child mishap, or adult incontinence, knowing how to get rid of urine smell quickly can save furniture, clothing, and peace of mind.
Here’s exactly what causes that lingering odor, how to neutralize it for good, and how to prevent future smells with the right cleanup and protection strategy.
Why Urine Smells—and Why It Lingers
Urine odor comes from uric acid crystals that form as the liquid dries. These crystals trap bacteria and release ammonia whenever moisture hits them again. That’s why old stains can suddenly smell stronger on humid days or after cleaning with water alone.
To remove the smell completely, you must break down those crystals, not just cover them up with fragrance or detergent.
Step 1: Blot the Source—Don’t Rub
First, absorb as much fresh urine as possible using paper towels or a clean white cloth. Press firmly to lift moisture without spreading it deeper into the fabric or foam. If the area is dry, mist lightly with plain water to reactivate the crystals before treatment.

Step 2: Use Enzyme Cleaner or Vinegar Solution
Enzyme cleaners are the gold standard—they digest the uric acid that causes odor. Saturate the spot and let it sit for at least 10–15 minutes before blotting again. Don’t rinse too early; the enzymes need time to work.
If you prefer a DIY route, mix one cup of white vinegar with one cup of warm water and a few drops of mild dish soap. Spray, wait, and blot dry. Vinegar neutralizes ammonia and helps release odor compounds trapped in fibers.
Step 3: Deodorize with Baking Soda
Once most moisture is gone, sprinkle baking soda over the area. Leave it overnight to absorb remaining odors, then vacuum thoroughly. For set-in smells, repeat once more after re-spritzing with vinegar solution.
This gentle chemical reaction neutralizes residual acids and leaves surfaces fresh without perfumes or masking agents.
Step 4: Dry Completely
Odor often lingers because moisture remains trapped deep inside. Use a fan or hair-dryer on cool to circulate air until the area feels fully dry. For large items like mattresses, set them near sunlight—the UV rays help kill bacteria and freshen naturally.
Step 5: Tackle Persistent or Mystery Odors
If the smell returns days later, the urine likely seeped deeper than surface cleaners reached. Apply an enzyme solution again, working it into seams or padding. For older accidents, professional extraction or ozone treatment may be needed to destroy stubborn odor molecules.
Clothing or bedding that retains odor after washing can be soaked in a solution of one part vinegar to three parts water for 30 minutes before laundering.
Prevent Future Urine Smells
Prevention saves more effort than any cleaner can. Protect high-risk areas and manage leaks before they start:
• Use a waterproof mattress protector to block absorption.
• Wash bedding weekly in hot water with a cup of white vinegar.
• For adult incontinence, choose breathable, leakproof protection from Underx.

Removing Pet Urine Smell
Pet urine contains more concentrated ammonia than human urine, making it especially stubborn. Use enzymatic cleaners labeled for pets, and avoid ammonia-based products—they can actually encourage re-marking. After cleaning, apply baking soda, let sit overnight, and vacuum. Repeat as needed until the scent is completely gone.
Deodorizing Fabric, Upholstery & Carpet
Blot, treat, and sprinkle baking soda as above. For removable covers, wash with oxygen bleach (if safe for fabric) and dry in direct sunlight. Steam cleaning helps lift deep odor from carpets when paired with enzyme pretreatment.
For lingering household odors after accidents, open windows and run fans—the simplest way to refresh air circulation.
Long-Term Odor Prevention for Incontinence
When leaks are frequent, even small drips can accumulate in furniture or flooring. The solution is reliable absorbent protection and smart hygiene habits:
• Change briefs promptly after use.
• Wipe the skin with pH-balanced, unscented wipes.
• Dispose of used products in sealed bags.
• Keep spare protection in travel kits or bedside drawers.
