How to Get the Smell of Wee Out of Clothes: Complete Guide (2026)

Quick Answer: To get the smell of wee (urine) out of clothes, rinse the fabric in cold water immediately, then soak it for 30 minutes in a mixture of cold water and white vinegar (1 cup vinegar per gallon of water). Wash on the hottest setting the fabric allows with regular detergent plus half a cup of baking soda. Avoid the dryer until the smell is completely gone, as heat sets urine odors permanently.

Why Urine Smell Is So Hard to Remove

Urine contains uric acid crystals that bind tightly to fabric fibers. When urine dries, bacteria break it down and release ammonia — that’s the sharp, unpleasant smell. Regular washing often isn’t enough because:

• Uric acid crystals are not water-soluble once dried
• Heat from dryers bonds the crystals to fabric permanently
• Bacteria keep producing odor as long as any residue remains

The key is acting fast and using the right combination of treatments.

Step-by-Step: Removing Urine Smell from Clothes

Step 1: Act Immediately

The sooner you treat urine stains, the easier they are to remove:

1. Blot, don’t rub — Use paper towels or a clean cloth to absorb as much liquid as possible. Rubbing pushes urine deeper into fibers.
2. Rinse with cold water — Hold the stained area under cold running water for several minutes. Never use hot water first — heat sets the stain and smell.
3. Remove excess — If the clothing is heavily soaked, wring it out gently after rinsing.

Step 2: Vinegar Soak (The Most Important Step)

White vinegar is the single most effective household treatment for urine odor:

• Fill a basin or sink with cold water
• Add 1 cup of white distilled vinegar per gallon of water
• Submerge the clothing completely
• Soak for at least 30 minutes (overnight for stubborn smells)
• The vinegar’s acidity breaks down uric acid crystals and neutralizes ammonia

Why vinegar works: Its acetic acid dissolves the alkaline uric acid salts that cause lingering odor. It’s also antibacterial, killing the bacteria that produce the smell.

Step 3: Baking Soda Boost

After the vinegar soak:

1. Drain the vinegar water (don’t rinse yet)
2. Sprinkle baking soda generously over the affected area
3. Let it sit for 15-20 minutes
4. Baking soda absorbs remaining odors and acts as a mild abrasive cleaner

Step 4: Machine Wash

• Wash on the hottest water setting the fabric can safely handle (check the care label)
• Use your regular detergent
• Add half a cup of baking soda to the wash cycle
• For very stubborn smells, add half a cup of white vinegar to the rinse cycle
• Use an extra rinse cycle if your machine has one

Step 5: Air Dry (Critical!)

Do NOT put the clothes in the dryer until you’re sure the smell is gone. Dryer heat permanently sets any remaining urine odor into the fabric. Instead:

• Hang clothes outside in sunlight if possible (UV rays kill odor-causing bacteria)
• Or hang indoors in a well-ventilated area
• Sniff test when completely dry — if any odor remains, repeat the vinegar soak

Special Cases

Dried/old Urine Stains

For stains that have already dried and set:

1. Soak in an enzyme-based cleaner (like Nature’s Miracle or Biokleen Bac-Out) for several hours
2. Enzyme cleaners contain bacteria that literally eat the uric acid crystals
3. Follow with the vinegar soak and hot wash described above
4. You may need to repeat 2-3 times for old stains

Delicate Fabrics (Silk, Wool)

• Don’t use hot water — stick to cool water
• Use a gentle enzyme cleaner instead of vinegar (vinegar can damage some delicates)
• Hand wash gently
• Lay flat to dry

White Clothes

• After the vinegar treatment, you can add a small amount of hydrogen peroxide (3%) to the wash
• Or use an oxygen-based bleach (like OxiClean) — never chlorine bleach on urine stains, as it reacts with ammonia to create toxic fumes

Products That Actually Work

Best household items:
– White distilled vinegar (cheapest and most effective)
– Baking soda
– Hydrogen peroxide (3% solution)
– Dish soap (a few drops in the soak for extra cleaning power)

Best commercial products:
– Enzyme-based pet stain removers (work on human urine too)
– Oxygen bleach (OxiClean, etc.)
– Borax (add half a cup to the wash)

What NOT to Do

• Don’t use hot water first — it sets the stain
• Don’t use the dryer until the smell is completely gone
• Don’t use chlorine bleach — it reacts with urine’s ammonia
• Don’t use ammonia-based cleaners — urine contains ammonia, so this makes the smell worse
• Don’t just mask with scented detergent — the smell will come back

Prevention Tips

• For potty-training children: use waterproof mattress protectors and keep spare clothes handy
• For elderly care: wash soiled clothes promptly, don’t let them sit in a hamper
• For pets: address accidents immediately with enzyme cleaner

Frequently Asked Questions

Will the vinegar smell linger on clothes? No. The vinegar smell completely disappears once clothes are dry. What remains is odor-free fabric.

Can I use apple cider vinegar instead? White distilled vinegar is better — apple cider vinegar can stain light fabrics.

How do I get urine smell out of clothes that have been through the dryer? It’s harder but not impossible. Soak in enzyme cleaner overnight, then do the full vinegar + baking soda + hot wash treatment. You may need multiple rounds.

Does sunlight really help? Yes! UV rays are a natural disinfectant and deodorizer. Hanging urine-treated clothes in direct sunlight for a few hours makes a noticeable difference.

Conclusion

Removing urine smell from clothes is straightforward if you follow the right order: cold rinse, vinegar soak, baking soda, hot wash, air dry. The biggest mistake people make is using heat too early. Be patient, skip the dryer until the smell is truly gone, and your clothes will come out fresh and odor-free.
