How to Get Rid of Human Urine Smell from Your Sofa缩略图

As mortifying as it may be, accidents happen. If you’re struggling to remove the stubborn urine smell left behind on your sofa, don’t stress. With the proper cleaning methods and odor-busting products, you can permanently eliminate that unpleasant human pee odor from your couch.


Why Urine Smells Linger

The pungent smell lingering long after the accident occurs because urine is more than just water and waste. It contains a complex cocktail of compounds that give it that unmistakable stench:

  • Ammonia: Formed when bacteria break down the urea in urine. Ammonia has a harsh, nostril-burning odor.
  • Volatile organic compounds: Various sulfur-containing compounds give urine its characteristic smells.
  • Bacteria: Microbes that feed on urine compounds produce their own smelly metabolic byproducts.

These substances easily soak into porous upholstery fabrics, becoming trapped deep within the fibers and foam cushioning. Even after the urine is cleaned away, these odor-causing compounds remain behind.

But with the right cleaning methods, you can destroy the bacteria, break down the volatile compounds, and absorb the ammonia to permanently purge the urine odor.

Cleaning Tips to Remove Urine Smell from Sofas

Eliminating urine odors requires attacking the smell on multiple fronts. Follow these steps to kick that pee smell to the curb:

Blot Fresh Accidents

For new accidents, immediately start blotting the urine with absorbent cloths and paper towels. Avoid rubbing, which presses urine deeper into the fabric. Blot until no more liquid transfers to the towel.

Rinse With Water

Grab a spray bottle filled with cool water. Spray liberally over the accident area and blot some more. This rinses away excess urine trapped in the fibers.

Apply an Enzyme Cleaner

Enzyme cleaners work wonders on tough urine odors. Enzymes break down the compounds that cause odors. Generously spray the area with an enzyme cleaner formulated for urine, ensuring you soak the padding beneath the fabric.

Let Enzymes Soak In

After applying the enzyme spray, allow it to soak in for 5-10 minutes. This gives the enzymes time to fully work their magic on the entire depth of the fabric.

Blot Away Enzyme Cleaner

After enzymes have soaked, use fresh absorbent towels to blot the area again. Press towels directly into the fabric to lift away cleaning solution and loosened urine residue.

Rinse with Vinegar

Mix one part white vinegar with two parts water and transfer to a spray bottle. Vinegar neutralizes odor-causing ammonia. Lightly mist the sofa with vinegar solution and let sit briefly before blotting.

Sprinkle Baking Soda

Baking soda is a natural deodorizer. Spread a thin layer over the entire sofa allowing to sit for 15 minutes before vacuuming away. The baking soda will help absorb any lingering odors.

Run a Wet/Dry Vacuum

For sofas with cushions, use the hose attachment on a wet/dry shop vac to suck up moisture and residue from the padding and crevices inside cushions.

Consider Steam Cleaning

Renting an upholstery steam cleaner can help deeply penetrate, loosen and sanitize urine odors if they’ve set into thick cushions and fabrics.

Mask with Essential Oils

A few drops of essential oils like lemon, lavender, or tea tree on cotton balls can help mask any faint urine whiffs that still remain. Just don’t overdo it.

Call in the Professionals

For severe urine odor issues, professional upholstery cleaning services have the high-powered tools, cleaning solutions, and sanitizing methods to fully eliminate those stubborn urine smells.

Preventing Repeat Occurrences

No one wants their beautiful sofa to become a frequent urine target. Here are some ways to avoid repeat accidents:

  • Scotch guard fabric protectors can help repel liquid absorption into your sofa’s fabric. Reapply every few months.
  • Nature’s Miracle or Kids ‘N’ Pets make waterproof, reusable covers to place over sofa cushions for extra protection.
  • If certain family members are prone to accidents, cover the sofa with a large, washable blanket or slipcover for easy removal.
  • For nighttime accidents, use disposable or washable pads designed for incontinence on top of the sofa cushions in problem areas.
  • Limit fluid intake before bedtime for those prone to middle-of-the-night accidents. Establish a clear bathroom path with nightlights.
  • See a doctor if accidents are frequent or new for an adult. This could signal an underlying medical issue.
  • For pets, restrict access to the sofa or use belly bands for male dogs to catch surprise leaks.


With some elbow grease and the right cleaning concoction, you can permanently eliminate embarrassing urine odors from your sofa. Just be sure to take preventative steps, so you don’t have to repeat this smelly process again soon.
