How to Remove Urine Smell from Your Couch

How to Remove Urine Smell from Your Couch

As much as we love our dogs, cats and small humans, accidents can happen on our upholstery, making our favourite sofa look – and smell – nasty.

It isn’t curtains for your couch though, no matter how bad the smell is or how many times it has been contaminated. We’ve got some tips to tackle that stubborn stench yourself and let you know when it might be time to call in the professionals.

What Creates that Urine Smell?

Removing urine smells can be tough, returning to haunt you days or weeks after you’ve declared yourself the victor against the formidable urine stain. There’s nothing ‘wee’ about them. Urine is a waste-product, containing a number of ingredients, including bacteria. The problem child in this ingredient list though, is uric salts, which cannot be broken down by anything other than an enzymatic cleaner.

What You Can Do to Treat Urine Stains

Remove the offending cushion (if you can) from the rest of the lounge.

If it’s a fresh stain, blot with a paper towel or old rag as much as you can. Some research suggests putting the dirty towels where your pet should be doing their business, as a positive reinforcement.

You should always test any cleaning product on a hidden section of your lounge fabric before proceeding.

Mix a 1:3 parts vinegar and water solution in a spray bottle, and spray generously on the stain. Scrub lightly before letting dry. Note: a dried stain will need much more of the vinegar/water solution, to re-wet the stain. Vinegar works well during this step because of its disinfecting properties.

Once the cushion is dry, sprinkle Bi-Carb Soda on the stain to help remove odours. You’ll need to leave the Bi-Carb on for a few hours before vacuuming up.

This will remove much of the stain and help with the smell. It won’t remove 100% of the stain though, which is why you need an enzymatic cleaner.

Enzymatic cleaners work because they break down the chemicals in the urine which cause the smell. Just make sure you follow the instructions closely and use a cleaner suitable for your upholstery type. Invest in a high-quality product to avoid having to re-do the job.

A few examples of effective Enzymatic cleaners are Natures’ miracle Urine Destroyer and Integrity Health. Electrodry sells a unique product called E-Pet that treats the urine odour and breaks down the uric salts, whilst leaving a long acting deterrent to help prevent the animal from returning to same location for a toilet visit in the future.

What If I Can’t Remove The Urine Odour?

Urine is a surfactant which means it breaks down surface tension. This means that the urine may penetrate deep into the padding of your sofa, especially if the pet has had multiple accidents in the same area.


If the urine has penetrated into the padding then topical treatments such as those that we’ve described above are unlikely to treat all of the uric salts, which means the odour is likely to return. In this case we need to inject a solution into the padding of the lounge to dissolve the uric salts, which is a job for the professionals. 

What Does Electrodry Do?

Chances are, you’d rather leave it to a professional to avoid potentially damaging the furniture or for the peace of mind that the stain or smell won’t come back. A professional clean is a great option if you have particularly delicate fabric or a stubborn stain and stench. Here’s the Electrodry difference.

  • If required, we’ll do a colour test on your fabric to ensure that the treatment doesn’t make the fabric colour run.
  • We can detect moisture in your couch using special equipment, so we know where to focus the spot treatment.

  • We’ll do a pre-vacuum with our industrial-strength equipment to ensure that any debris is removed from your couch.
  • We will inject a solution into the affected are of the couch to treat the uric salts.

  • A qualified technician will apply a pre-spray solution, which contains antibacterial and sanitising properties.
  • We apply a specialised upholstery cleaning spray, which includes Healthguard, a strong sanitiser that removes odour-causing bacteria, germs and fungi.

We can treat most stains and odours and offer a 14-day guarantee on our upholstery service. Please note, it really helps if you know what the stain is and roughly when it occurred – that’s how we know what chemicals are best to treat it with.

Important Notes:

The greater the level of contamination, the harder it becomes to treat all of the uric salts and remove the odour. If the lounge has been contaminated on multiple occasions, then replacement may be the best option. It is also important that we point out that old urine stains on cotton fabrics can be very difficult, if not impossible, to remove.
