How to get Human Urine out of Carpet (The scientifically proven solution)

I am sure you will agree there is nothing worse than the smell of day old urine on a home carpet. If the room is closed off or the temperature is really warm, the smell increases to the point where you won’t even want to enter the room.

Unlike other types of stains, removing human or pet urine from carpet cannot easily be done using a home remedy.

Accidents happen – especially when you have a toddler going through potty training. But it doesn’t just have to be from young children. It may be an incontinent adult or your family pet.

The reason this type of stain is so difficult to remove is that the urine forms crystals of uric acid just below the carpet surface that doesn’t break down with water or most conventional home treatments. Traditional soap and strong chemicals don’t have the ability to break down the crystals and the smell remains.

WARNING!

Don’t use vinegar, baking soda or soapy water on this type of stain. It won’t work and vacuuming baking soda can damage your vacuum cleaner.

Instead, you are going to need a spray that contains the correct combination of enzymes to destroy the crystals and to neutralize the stain. The spray will kill the bacteria that causes the smell and make your carpet smell like new again.

This is one of those unique cases, where a product designed to clean up after pets will also work perfectly well on human urine.

How to get human urine smell out of carpet

Step 1

Soak up as much of the urine as possible with a paper towel. Use the back of an old shoe to push the towel into the stain. The more you can remove, the better the final result will be. If the stain is old, the paper towels won’t be able to pull any liquid out.

If you decide to use cotton or fabric towels, make sure you don’t put the towels in the wash. Instead, put them in a bucket or your bathtub and cover them with warm water, laundry detergent, and baking powder. You need to wring them out well before putting them into the washing machine.

Step 2

Get a spray bottle of enzyme cleaner.

We can recommend the Sonny and Honey Pet Stain and Odor Miracle spray bottle. It normally goes for just under 20 dollars.

Don’t worry that the bottle says it is for use on pet urine. It also has everything you need to clean up a human urine accident.

With more than 3,200 positive reviews, this product is extremely well proven and worth every penny. If this is a problem that may occur again in the future, you may want to invest in the one-gallon bottle.

Spray the area where the urine lays and allow the enzyme liquid to sit for at least 10 minutes. This will give the liquid time to start breaking down the uric acid crystals.

Step 2

Wet a clean towel with warm water and gently scrub the area where the cleaner is. You will need to do this a few times and it is recommended that you change the water between rounds of cleaning. You don’t want to use a soiled towel on an area you are trying to clean.

The following video from the manufacturer shows how to use the spray bottle and how to clean the area with a paper towel.

The spray contains enzymes that are dormant until the cleaner is used on an organic stain or odor. They do their job by eating away at the stain and finally drying up and disintegrating when the job is done.

Step 3

Remove the remaining liquid using paper towels or, if you have access to a wet vacuum cleaner you can suck up the remaining wet spots.

For old stains

If a stain has been sitting for more than a day or two, you will want to go with a stronger cleaning option.

If it is a one-off clean, you could use a commercial solution like the "Rug Doctor".

However, if you have a wet vacuum cleaner, you can clean the carpet with warm water and the Sunny and Honey Carpet Miricle solution which is designed to go into most wet and dry vacuum cleaners.

In this case, use your vacuum cleaner according to the manufacturer’s instructions.

The following video from Sunny and Honey shows how to use the liquid in most wet and dry vacuum cleaners.

Frequently Asked Questions

How much cleaning product do I need to use?

Always read the instructions on the bottle. However, keep in mind that most products are designed to be used on cat and dog urine. Humans produce a lot more liquid (but not as concentrated). You will need to adjust the quantities to take this into consideration.

As a rule of thumb, use a similar amount of liquid to the amount of urine you are trying to clean up. If you are unsure, you can do multiple treatments over several days until the smell is gone.

Remember the urine is normally deeply embedded in the carpet, and you will need to apply a good amount of liquid to allow the enzyme to soak in. You should always ensure that you spray beyond the outline of the visible stain to be sure you have treated all of the uric acid.

What happens if it still smells after the treatment?

Normally the smell gets worse before it gets better. As the uric acid is pulled to the surface, the smell is released into the air.

If it still smells after a couple of days, you probably need to use more stain remover. You also need to make sure you have properly dried the area after using the spray or liquid. Even though the surface may seem dry, often the underlay is still wet and you may need to lift the corner of the carpet or apply pressure with a dry paper towel to pull the remaining liquid out.
