E.J. Wheaton Pet Stain Odor Eliminator Professional Strength Enzyme Aerosol 20oz Review (2026)

Who this can is built for

E.J. Wheaton markets this as a professional strength cleaner, and the manufacturer says it is used in veterinary offices, shelters and doggy daycares as well as homes, which points to a formula meant for stubborn, set-in odors rather than light touch-ups. For an apartment household that deals with the occasional accident from a dog or cat, a can under the sink covers spot treatment on carpet, upholstery and hard floors without needing a bulkier jug. Because it ships as a 20oz aerosol rather than a 32oz or gallon pump bottle, it suits a single pet or light use better than a home with several animals that would need to restock more often. Renters who want something that will not leave a dye stain on light colored carpet or furniture are the main audience here.

What is actually in the can

The manufacturer describes the formula as bio-enzymatic, meaning it relies on enzymes that break down the proteins in urine and other organic pet messes rather than just masking the smell with fragrance. E.J. Wheaton states the product is dye-free and bleach-free, and says it is tested and approved for use on carpets, furniture, fabrics and hard surfaces. The can is pressurized so it dispenses as a thick foam instead of a thin liquid spray, and the manufacturer notes the nozzle is designed to work even when the can is held upside down, which matters for reaching low spots on a wall or the underside of furniture. This puts it in the same enzyme cleaner category as pump spray competitors, with the aerosol foam format as the main point of difference.

Living with it day to day

Directions from the manufacturer call for shaking the can before use, then spraying in short bursts until the stain or spot is well saturated with foam. Because it is a foam rather than a liquid, it tends to sit on top of carpet fibers and upholstery instead of soaking straight through to the padding underneath, which can help it stay concentrated on the mess. E.J. Wheaton's instructions note that stubborn odors may need more than one application, with time to dry between passes. One practical limitation worth knowing before buying is that aerosol cans cannot be refilled or topped up, so once the 20oz is empty the entire can is discarded, unlike a reusable pump bottle that some owners refill from a larger jug.

How it stacks up against rivals

In this site's pet odor eliminator lineup, this product lands at the bottom of the ranked group, and the 20oz aerosol size is a big part of that. Competing enzyme cleaners in the same roundup, including a 32oz citrus oil formula and a 32oz cleaner from another enzyme brand, hold well over 50 percent more product per bottle at a similar or larger size, which lowers their cost per treatment for owners cleaning up regularly. Those rivals also use standard pump triggers that can be refilled, while this aerosol format cannot. The trade-off is that the foam clings to vertical surfaces like walls and door frames better than a thin liquid spray would, which is a genuine advantage for accidents that happen against furniture or baseboards rather than flat on the floor.

Bottom line

This is a reasonable choice for a renter who wants a professional strength, dye-free and bleach-free enzyme spray for occasional pet messes and likes the idea of a foam that clings rather than runs. It is not the most economical option in this category because the 20oz aerosol holds less product than the larger pump bottles it competes with, and the can cannot be refilled once it is empty. Owners with multiple pets or frequent accidents to manage will likely get more value from a 32oz pump spray enzyme cleaner instead, saving this option for smaller households or as a backup can for vertical surfaces.
