Best carpet cleaner for old pet urine

Last update 6th December 2019

Why old pet urine is too difficult to clean with casual formula

All of us are aware that old pet urine and stains are very difficult to clean. The first reason is that once the urine set in the carpet fibers for a duration, it attaches to the fibers and unable to be removed by casual cleaners like detergents or carpet cleaning solution.

The old pet urine (ammonia crystals) needs a special chemical substance to break down the molecular connection from the fibers. There are a few commercial substances available for cleaning old urines thanks to oxidative reactions or enzymatic reactions.

Oxidative (chemical) carpet cleaner

This type of cleaning formula uses a strong oxidative substance like Clo, Javel to break down the urine molecules. Chemical cleaning formula is often very effective, however, it can also discolor your carpet and ruin organic carpet types like Linoleum, Kashmir, Oriental rugs.

Before using the chemical formula for removing old urine and old stains, you have to test on a small area to see if the carpet is safe for cleaning. 

After cleaning, you should wash the carpet entirely to avoid the risk of swallowing (if you have pets around)

Enzymatic carpet cleaner

The organic-based cleaning formula, the enzymatic carpet cleaner is a trending cleaner in recent years, regarding the safety of personal use and environmental ethic.

This type of cleaning formula uses dormant bacteria capable of digesting the urine. When the dormant bacteria meet the urine, it will become active and consume the urine and finally remove the odor.

Both of the above cleaning formulas are very common and affordable. However, the use and the benefits of them are not the same.

Chemical carpet cleaners are often cheaper, more popular, fast and effective. Most of the synthetic carpets are suitable for this type of cleaner. 

The drawback of chemical carpet cleaners is: not environmental-friendly, not suitable for organic materials, hazardous if swallowing.

The enzymatic carpet cleaner is environmental-friendly, safe for users and effective too. However, it will take a long time for the bacteria to work on the urine and stains.

How to choose between chemical cleaner vs enzymatic cleaner

You can choose the chemical cleaner when
