How to Remove Pet Urine Smell from Your Couch (and Keep It from Coming Back)
Pet ownership comes with many joys — but one of the biggest headaches? When your beloved dog or cat leaves behind that unmistakable urine odour on the couch. It’s a problem many Australian households face, and unfortunately, regular cleaning methods often fall short. This guide will help you understand why the smell lingers, how to remove it effectively, and how to stop it from returning — so your home can stay fresh, clean, and pet-friendly.
Why Pet Urine Smell Is So Persistent
Pet urine contains ammonia, uric acid, and bacteria. While the liquid may dry, the uric acid crystals remain embedded deep within the fabric and cushions, releasing odour every time moisture or humidity reactivates them. According to research on urine chemistry (Wikipedia, 2025), these crystals require enzymatic breakdown — not just soap and water — to be fully removed. Recent data from the 2025 Australian Pet Owners Survey shows nearly 70% of households report odour returning after superficial cleaning.
Step-by-Step: Removing Pet Urine Smell from Your Couch
Blot immediately
If the accident is fresh, use paper towels or an absorbent cloth to blot — not rub — the spot. Rubbing will push the urine deeper into the fabric.
Apply enzyme-based cleaner
These specialised cleaners break down uric acid at the molecular level, unlike soap, vinegar, or baking soda, which only cover up the smell.
Treat the inner cushion
If your cushion covers are removable, unzip and clean the foam inside. Urine often penetrates deeper than you think, and skipping this step leads to lingering odour.
Rinse with diluted vinegar
A 1:1 mix of white vinegar and water neutralises surface ammonia and reduces bacteria.
Dry thoroughly
Bacteria thrive in moisture. Use fans, a hairdryer, or sunlight to ensure everything is fully dried.
Optional: Apply baking soda overnight
As a finishing touch, sprinkle baking soda over the area, let it sit overnight, and vacuum it off the next morning for added freshness.
The Long-Term Solution
Even with perfect cleaning, pets are unpredictable. That’s why investing in a high-quality, waterproof sofa cover is the most effective long-term strategy. Not only do these covers block liquids from reaching the fabric, but they are machine washable and designed to blend seamlessly with your home’s style.
