Why the Urine Odor Persists

Why does urine on carpet create such a strong smell? As the urine dries, it forms crystals, and these crystals are the source of the odor. Urine stains also encourage the growth of bacteria, which contributes to the smell. When these remnants become trapped in the carpet fibers, under the carpet, in the padding, and even in the subfloor, the odor lingers until they are removed.

Detecting Pet Urine Stains

If you’re fortunate, you may witness the accident and know exactly where to clean right away. A fresh accident will still be wet, which makes it easier to locate the affected area. But what about older urine stains or spots that you miss?

A UV light is a useful tool for identifying all the urine stains in your carpet. Shine the UV light across the floor in various areas to locate dog urine on carpet and other surfaces, such as baseboards and walls. The light reveals any urine stains, making them easy to spot.

Absorbing Fresh Urine

For a wet urine spot, start by absorbing as much urine as possible before it dries and seeps deeper into the padding. Use a cloth or paper towel to blot the area, but avoid rubbing the fabric. Continue blotting with clean cloths or fresh paper towels to remove as much urine as you can.

You can also use baking soda or corn starch to help absorb the urine. Sprinkle the powder over the wet area, ensuring complete coverage, and let it sit for at least 30 minutes. Vacuum up the baking soda or corn starch. You may need to use other cleaning methods to completely eliminate the stain and odor, but absorbing some of the urine initially simplifies the task.

Utilizing a Wet Vac or Water

Renting a wet vac can be helpful in removing a significant amount of the dog urine odor from your carpet. Clean the carpet with the wet vac according to the manufacturer’s instructions using plain, clean water. If you don’t have access to a wet vac, you can blot the area with clean, cool water using clean cloths. Use dry cloths to absorb the water and dry the carpet.

Do not mistake a wet vac for a steam vac. Using a steam vac will actually set the urine stain and odor due to the heat. A steam vac can make the problem worse.

Use Enzymatic Cleaners for Cleaning

An effective solution for eliminating old pet urine or stubborn stains on carpets that cannot be removed with water alone is to utilize enzymatic cleaners. These cleaning products aid in neutralizing unpleasant odors by breaking down the urine molecules. It is important to carefully follow the instructions provided by the cleaner, as it often requires sufficient time to sit on the stain in order to effectively work. In some cases, multiple applications of the cleaner may be necessary to completely eliminate the odor.

If your carpet has previously been cleaned with another type of cleaner, it may hinder the effectiveness of the enzymatic cleaner. It is recommended to use this type of cleaner after utilizing a wet vac with plain water, as it can help enhance its performance.

Eliminating Pet Odor in Carpet Pad

If the urine manages to penetrate through to the carpet pad, it can be challenging to eliminate the odor using cleaners alone. Regular surface carpet cleaners are unable to reach the urine crystals and bacteria that are trapped beneath the carpet in the pad and subfloor. In order to completely eradicate pet odor from the carpet pad, it is often necessary to remove the carpet and replace the pad.

In certain instances, the urine can seep through to the subfloor, resulting in stains and trapping the odor within the wood. When removing the carpet and padding, it is advisable to inspect the subfloor for any indications of urine stains. In some cases, it may be necessary to remove the urine-stained section of the subfloor and replace it with new wood in order to completely eliminate the odor from your home.
