The problem with urine accidents in carpets

Pet odor Removal

Urine accidents in the carpet tend to be some of the more difficult accidents to treat because of the volume of fluid that is deposited into the carpet and how deeply they penetrate. A quick wiping up of the mess and spraying of a pet odor eliminator might appear to take care of business, but in reality, you’ve only scratched the surface of  what is needed for pet odor removal.

When these accidents occur, the urine saturates not only the fibers on the surface of the carpet, but also the. Based on the average carpet / pad thickness and typical amount of fluid that will be absorbed, ½ cup of hot urine will penetrate down to the sub-floor beneath the carpet/pad and spread into a circular pattern nearly a foot wide. If the animal continues to urinate in the same area, over time, the area involved tends to spread these deep hidden spots into wider areas contaminating more of the pad, sub-floor, and backside of the carpet.

When urine is allowed to dry and remain in the carpet or other material, the proteins and salts in the urine begin to bond themselves to the fibers. The longer it is allowed to remain, the stronger the bond becomes.

Effective treatment of urine accidents in carpets

Pet stain and odor removalWith any accident, the first most important step is to remove as much of the accident as possible. If it is urine, blot it up with a paper towel; if it is feces or vomit, dispose of as much of the solid matter as possible and also blot with a paper towel. Using disposable latex gloves makes it a less unpleasant task. Prior to using a bacterial/enzyme digester, always test a less conspicuous spot of your carpet for color fastness.

One of the biggest problems using odor eliminator products is not using enough of the product for satisfactory results. If the odor eliminator product does not get to the entire area affected, the area will not be completely treated. Also, it is very important that you allow the carpet to air dry, and not use fans or heat to speed up the drying process. Speeding up the drying process decreases the effectiveness of the product.

If you are able to lift the carpet, spray both sides of the carpet as well as the padding and floor. Any object where urine is should be sprayed, including walls. If you are unable to gain access to contaminated carpet from both sides, the best way to treat the area is by injecting directly into the contaminated area with a high-quality bacterial/enzyme digester such as Anti-Icky-Poo ( or Nature’s Miracle ( Saturating the area from the top is easier to do, but less efficient and somewhat less effective. In carpeting, the bulk of urine is normally underneath in the carpet backing, pad and floor below.

Injecting the bacterial/enzyme digester into carpets

Injecting the bacterial/enzyme digester below the carpet is the most efficient way of using the product. This is accomplished with a large syringe and needle, which is used to inject the solution to the affected area. This is performed by piercing the carpet backing with the needle and lifting the tufts of the carpet with your other hand. The needle is slide in horizontally between the secondary backing and the top of the pad. Then about 30 milliliters of the bacterial/enzyme digester is injected into the space between the carpet and the pad. The procedure should be repeated each four to six inches in the contaminated area until you have adequately treated the entire area. You can expect that 30 milliliters will cover a four to six inches area depending on density of the fabric and thickness of the pad. Typically, you will have to refill your syringe many times.

Spraying or pouring the bacterial/enzyme digester into carpets

If you are not injecting bacterial/enzyme digester below the carpet, make sure to get the liquid into the padding because that is where 90% of the urine is. To do this, spray the surface and walk on the area with your full weight, in order to spread and squeeze in the bacterial/enzyme digester down to the pad, sub-floor, and backside of the carpet. The other option is to pour the bacterial/enzyme digester directly onto the area at full strength. Use enough to completely saturate the area including the padding and subfloor. The carpet should be soaking wet. Allow it to sit for about 20 minutes, and then blot the product up. In general, it takes about 1 pint of bacterial/enzyme digester to treat a one-square-foot area.
