Why Is Urine Smell Hard To Remove From Carpet?

One of the reasons that it is so hard to remove the smell of urine is because of how this natural body fluid is composed and the construction of most carpets. Over time, urine breaks down and leaves behind residue deep in carpet fibers.

Additionally, even after cleaning carpet at the surface level, ammonia and bacteria can sink to the lowest levels of a carpet's fibers and even sink into any padding underneath.

It is not uncommon to smell urine after shampooing, steaming, or water makes contact with the carpet. Moisture can easily reactivate the odor of urine, make the flooring smell musty, or cause odor-causing bacteria to proliferate.

How To Remove Urine Smell Explained

Urine is typically acidic, so it is wise to use alkaline agents to neutralize this substance. Many people choose to reach for vinegar or baking soda to penetrate the carpet fibers and find their way to any urine left behind.

When possible, try to treat urine stains and odors as soon as they happen. Older stains may eventually lose their power over time but can be reactivated when there is contact with wet commercial cleaning agents, water, tea, or coffee.

Moving quickly to remove urine and bacteria can reduce the chance of incurring foul odors from your carpet and padding in the future. However, you can use baking soda, vinegar, enzyme cleaners, or deodorizers for old problems.

Choose from the following to help lift urine from carpet and foul-smelling odors.

White Vinegar

Apply a 50/50 solution of water and white vinegar to the affected area of your carpet. Saturate the fibers of the carpet and agitate the flooring a bit. Allow the carpet to fully dry before resuming normal use.

If necessary, add two tablespoons of baking soda to your diluted solution of vinegar and water for increased cleaning power.

Baking Soda

Liberally douse your carpet and padding underneath with baking soda and allow to sit overnight or longer before removing with a vacuum cleaner. Be careful with baking soda, as the residue left behind could cause unwanted problems.
