Review of Spot Shot Pet Instant Carpet Stain and Odor Eliminator Trigger Formula

Spot Shot Pet Instant Carpet Stain and Odor Eliminator Trigger Formula is a cleaning product specifically designed to remove stains and odors caused by pet accidents. Its use is not limited to pet accidents, however, as the product states that it also works on tracked-in dirt and soil.

It is a brand of the WD-40 Company, which is headquartered in San Diego, California.

How is it different?

According to the manufacturer, there are several features that make Spot Shot stand out from its competitors.

Safe for Kids and Pets

Spot Shot Pet Trigger Formula is non-toxic, and is certified biodegradable by Scientific Certification Systems, Inc., an independent testing and certification company. According to the manufacturer, Spot Shot contains no phosphates and no Volatile Organic Compounds (VOCs). It is safe for use in households with children and pets (although the company cautions users to keep children and pets away from the area until it has dried).

Another point worth mentioning is that the product label states that it has not been tested on animals – a big plus in my books.

Protects Carpet

Another unique feature of Spot Shot is that it claims to protect the carpet on which it has been used, with Anti-Resoiling agents. Often, cleaners can leave behind a residue, which attracts dirt to the spot and causes soiling issues. Spot Shot’s water-based formula purportedly leaves no such residue behind, thereby reducing soiling in the area.

Product Uses

According to the manufacturer, Spot Shot Pet may be used to remove urine, feces, vomit, and tracked-in mud, dirt and oil from carpet.

Vomit Stains

My first experience with Spot Shot Pet was to use it after my cat vomited on my carpet. I followed the directions on the label, first scooping up the solid matter, and then blotting the area with white paper towels.

I then sprayed the area with the product.

Using paper towels, I very gently rubbed the carpet fibers, and was quite impressed to see the stain working its way out of the fibers as I did so. Within about a minute, there was no visible trace of the vomit remaining on the carpet. I followed by blotting up as much of the moisture as possible, with clean paper towels, and then finished by brushing the carpet lightly with my hand.

The result: the stain was almost completely undetectable. I could notice the spot that had been treated, but only because the carpet fibers were still a bit damp. When I returned the next day and inspected, the fibers that had been treated were indistinguishable from the rest.

My overall first impression: Very effective, and very easy!

Urine Odors

The product did not fare as well, however, when it came to eliminating urine odors. Since my pets are not prone to bathroom accidents, I placed a small square of scrap carpet in my cat’s litter box, and left it there for a few days. (The cat was pretty unhappy about it, and did his absolute best to make use of every square inch of the litter box except where the carpet was. Fortunately, a section of the carpet did get soiled with urine.)

I removed the piece of carpet and treated it all over with the Spot Shot Pet. I then left it for a day. Upon inspection the next day, I could still detect the smell of urine on the carpet, and had other family members verify that they could as well. So, I treated the piece once again, and again left it overnight. The following day, I gave it another sniff test, and unfortunately could still detect a vague urine scent.

I figured that putting the piece of carpet in the litter box may have been a fairly harsh experiment, so I enlisted the help of a friend whose elderly dog is prone to household accidents. My friend used Spot Shot Pet on the urine spots on her carpet, and reported that after treating all of the spots she could find, she could still detect a urine smell for several days. In the end, she opted to have her carpet professionally cleaned by hot water extraction.

Thus, from these two experiences, it does not seem that Spot Shot Pet fully eliminates urine odors.

The Final Verdict

Stain Removal: Excellent

Odor Elimination: Fair

From my experience, I would not hesitate to recommend Spot Shot Pet for use on pet vomit stains, and I believe it would likely work equally well on dirt and soil, as it very effectively removed the stain. However, I cannot say that it works to eliminate urine odors, and so I would not recommend it for that use.

If you have a pet who is more prone to being sick and tracking in dirt than to having bathroom accidents, this product would be a good choice. If you are looking for a product to get rid of the smell of urine, however, this is probably not the right product for you.
