Pet Urine 1


Pet urine

This is part one of a 2 part "Pet Urine, Scale of Severity" article.

Let’s create a scale to help us determine how severe the pet urine contamination is. We need a couple things in order to effectively correct dog urine stain and odor problems. We need to locate each of the problem areas. We also need an idea of how extensive or severe each of the problem areas are. This scale will help determine this. We will use 4 levels in this scale. Minor, Light, Moderate and Severe.  We will apply it to a carpet and pad scenario. The principles can be applied to other applications also. For example furniture, drapery, mattress’s and other fabrics. This scale will also be useful for concrete, hardwood, walls, tile and other hard surfaces. Not as useful as when applied to carpet and fabric but still useful. It is not much use for grass, lawn or plant damage.

Minor pet urine

This is where the dog has urinated only small amounts and you are able to blot (paper towels or absorbent rags) it or extract (wet/dry vac) it out before it can dry in the carpet.  A small amount may have reached the backing of the carpet but it has not reached the pad or the sub floor. However it does get into the face fibers of the carpet and it has not dried in the carpet.

Light pet urine

This is when there is a little more urine and you are not able to clean it up quickly. It soaks deeper into the face fibers and reaches the backing. But not into the carpet pad. If many deposits occurred in the same location the urine would likely have reached the pad and the floor below. In this case the contamination would no longer be described as light. Urine may or may not have dried in the carpet.

Moderate pet urine

Urine has soaked through the back of the carpet. Urine stains and/or alkaline salt crystals are apparent on the backing of the carpet. The carpet pad is contaminated and very possibly the subfloor/floor under the carpet. If the Tack strip (the strip used around the outer edged of the room to hold the carpet down) has been affected it is stained only but still in good condition. The lipids (animal fats in urine) left in the carpet are not enough to make the carpet fibers sticky.
