Hoover’s Pet Plus pet stain and odor remover is a very popular cleaning solution used by many pet owners in both carpet cleaning machines and as a spot treatment. Because we’ve read so widely that this product is recommended by many for a spot cleaner, we wanted to give it a try for ourselves and see how it did. While Pet Plus is still very popular as a standalone solution for tackling pet stains and odors, Hoover’s most recent enzymatic cleaning solution designed specifically for spot treatment is part of the Paws & Claws line of products.
About Enzymatic/Microbe Cleaners:
Hoover Pet Plus is in our enzymatic/microbe cleaner category, utilizing enzymes to break down the odor-causing compounds in pet urine. This eliminates the problem, instead of concealing or attempting to remove it. It is important to understand the difference between eliminating the substances that create the odor and stains versus cleaning them.
Pet urine contains uric acid, which crystallizes and is highly insoluble in water. Most cleaners do not remove uric acid, which breaks down over time into odor-causing substances. Cat urine, especially, as it can get oily and even more concentrated as it dries! Additionally, it may be more difficult to manually remove protein and amino acid components of urine, which your pet may smell (and be tempted to re-mark), even if you can’t. We think it’s best to attack the problem at the very root of the source- the chemical composition of the stench!
Hoover Pet Plus Put To The Test:
For our test, we used Hoover Pet Plus on medium-pile carpet to tackle dog urine. We wanted to simulate the most realistic conditions.
The dog urine was applied twice to the carpet, so there is a fresh and an older stain present.*
We know that cat urine can be more potent and pungent due to how concentrated it is, but the process is the same for removing cat urine as dog urine.
The ingredients in Hoover Pet Plus are:
Water, surfactant, C12-14 Alcohols Ethoxylated Propoxylated, Sodium Lauryl Sulfate, Bio-enzymatic Cleaner, antifoam, Fragrance, PEG-115M (a thickener), Polypropylene glycol monoallyl ether, Polyalkylene glycol monoallyl ether, C12-14 Secondary Alcohols, 1,2-benzisothiazol-3(2H)-one, Tetrasodium ethylenediamine tetraacetate, Potassium hydroxide, Phenoxyethanol, Isopropyl Alcohol, Dipropylene Glycol, p-Lysmeral, Hexyl cinnamic aldehyde, Linalol, Citronellol, Coumarin, Eugenol, Citral, Diethyl phthalate, D-limonene, Citric Acid, Geraniol, Hydroxy-methylpentylcyclohexenecarboxaldehyde, Cinnamyl alcohol, Benzophenone, Jasmin aldehyde.
According to Hoover’s SDS sheet for this product: “This mixture is considered hazardous by the 2012 OSHA Hazard Communication Standard (29 CFR 1910.1200).”
The instructions indicate to pretreat with this formula before diluting it for use in a carpet cleaner.
We did two applications of Hoover Pet Plus, 15 minutes apart, and observed under a black light.
The first application under the black light showed the urine (shows up bright yellow/greenish under the black light) disappearing slowly as the enzymes went to work. We blotted with a paper towel to help the material penetrate, returned 10 minutes later, and reapplied Hoover Pet Plus. After 5 minutes, we blotted again and began wiping it up with a clean rag.
Hoover Pet Plus did not penetrate very quickly and we think that’s probably because it’s a thicker formula, so we tried reapplying again with a little water added. It seemed to work a little better but required a lot of agitation with a rag to get it to penetrate to the base of the carpet. When we flipped it over, there was a significant amount of urine stain glowing under the light that had not been eliminated by the enzymatic cleaning action.
For spot treating/pre-treating with Hoover Pet Plus, we recommend putting the concentrate in a spray bottle and adding a very small amount of water. Because this is a toxic, highly fragranced formula, we also strongly suggest water extraction with a carpet cleaning machine. At the very least, we believe you should blot and extracting the cleaner from the area with a wet rag and clean water once you’ve removed the stain. If you have an item you are concerned may not be colorfast, this step should be done anyway. The surfactant in this product may attract dirt if it’s not removed from the carpet. It does have an anti-foaming ingredient but it was not very effective.
This has a fairly strong smell, that hangs around for over a week. There are a lot of synthetic ingredients that make up the fragrance so be sure you are not allergic to any of them. We don’t feel the toxic ingredients in this formula are worth the unexceptional cleaning power of this solution.
We rate Hoover Pet Plus at 4 out of 10 as a spot cleaner. It does much better in carpet cleaners such as the full-sized Hoover FH52000 or in the amazing new ONEPWR Cordless Carpet Cleaner.
- Have lots of paper towels and rags on hand.
- Plan ahead- An enzymatic cleaner can be part of your “Oops” kit assembled ahead of time with everything you need ahead of time to effectively and quickly attack any stains or problem areas.
- After you’ve treated the urine stain with an enzymatic cleaner, let it sit overnight, and come back and blot up any residue with clean water and a rag.
- If you are satisfied with the removal of the stain, go over the area thoroughly with a vacuum cleaner after it has dried to remove any residue left.
- Enzymatic cleaners can be augmented with baking soda sprinkled on carpets and furniture to absorb odors. Leave it at least 24 hours and then vacuum thoroughly.
- Always pretreat a rug or carpet with an enzymatic cleaner before using a carpet machine on it or having it professionally cleaned.
- Never use hot water to try and extract a urine or poop stain.
