Why trust this review
I am Dr. Emily Rhodes, and I have spent 14 years as an equine veterinarian working on everything from backyard ponies to show-ring Warmbloods and rescue rehab cases. I clean wounds for a living. I also live in the real world where a client cannot call me out at 9 pm for a hock scrape, so I think hard about what belongs in an owner’s barn first-aid kit between vet visits.
I bought this product with my own money and used it the way you would, not in a lab. My goal here is simple. I want you to know exactly when this spray earns its keep, when it is the wrong tool, and where your money goes furthest. I follow American Association of Equine Practitioners (AAEP) and American Veterinary Medical Association (AVMA) guidance on wound care, and nothing here replaces an in-person veterinary exam for a serious injury.

How I tested Vetericyn Plus Equine Wound and Skin Care Spray
I used one 16 oz bottle over three months across a mix of horses: my own 17-year-old Quarter Horse gelding, a thin-skinned off-track Thoroughbred mare boarded at my barn, a stocky Haflinger pony, and several clinic cases where owners consented to me trialing it for routine cleaning.
The wounds were the everyday kind owners actually deal with. Wire-fence leg scrapes, a girth-area rub, superficial pastern scabs from wet turnout, a few fly-bite sores, and one patch of early rain rot (dermatophilosis) on a topline. I tracked how each horse reacted to the spray sound and the liquid, how well it cleaned debris, how long it stayed put, and whether the skin underneath stayed calm or got irritated. I did not use it on anything deep or infected, because those go straight to a proper veterinary protocol, not a spray bottle.
The active ingredient is hypochlorous acid at roughly 0.012%, the same broad class of gentle cleansing chemistry used in a lot of modern wound rinses. It contains no antibiotics and no steroids, so I was comfortable applying it daily without the resistance or healing concerns those carry.
Who should buy, who should skip
Buy this if you want a gentle, no-rinse cleaning spray for minor cuts, scrapes, fly sores, and surface skin irritation, especially on horses that hate stinging products. It shines on sensitive Thoroughbreds, on faces and muzzles where you cannot use harsh antiseptics, and for owners who want something simple and forgiving in the tack room.
Skip it, or at least do not rely on it alone, if you are dealing with deep, gaping, or infected wounds, anything near a joint or tendon, or large body areas where you will burn through a bottle fast. For those, dilute chlorhexidine, sterile saline, and most importantly a phone call to your vet will serve you better. The AAEP is clear that deep, joint-adjacent, or non-healing wounds need professional evaluation, and I will not pretend a spray changes that.
Gentleness on skin: where it genuinely shines
This is the strongest part of the product and the reason I keep recommending it. On the off-track Thoroughbred mare, who normally pins her ears and lifts a leg at the first hiss of iodine, the spray drew almost no reaction once she got past the sound. Hypochlorous acid sits near neutral pH, so there is no alcohol burn and no iodine sting.
For owners of thin-skinned breeds, sensitive Arabians, or any horse that has learned to dread wound care, that gentleness is not a luxury. A horse that stands quietly gets cleaner wounds and fewer fights. I scored this a 9.3 because in three months I did not see a single irritation reaction underneath, even with daily use on the Haflinger’s pastern scabs.
Everyday wound cleaning: solid for the minor stuff
For surface debris and routine flushing, it does the job. I would spray to soak a scab or loosen dried dirt, give it a minute, then wipe with clean gauze. On the early rain rot patch, daily cleaning paired with keeping the area dry helped me lift crusts without scrubbing raw skin, which matters because dermatophilosis spreads when you traumatize the area.
I want to be precise about claims here. I am describing cleaning and a calm healing environment, not a cure. The AVMA and AAEP both stress that wound outcomes depend on depth, contamination, and overall care, not one product. What I can say honestly is that it cleaned reliably and the skin stayed healthy-looking under it.
Ease of application and coverage: the trigger is the catch
Application is easy in theory and occasionally annoying in practice. The trigger sprayer puts out a fine mist, but that same hiss made my normally bombproof Quarter Horse fling his head the first few times. With nervous horses I switched to spraying onto gauze or a cotton pad and wiping the wound, which solved the startle problem entirely. I would build that habit from day one with any reactive horse.
The liquid itself is watery, which is both good and bad. It flushes nicely but runs right off vertical surfaces like the front of a cannon bone and dries faster than an ointment. On a lower leg I sometimes had to reapply more often than I would with a salve. That cost it points on staying power, landing it at a 7.0 there.
Measurements that matter
A few concrete numbers from my three months. One 16 oz bottle lasted me roughly the full period using it on minor wounds across several horses, but I would have emptied it in two to three weeks if I had been flushing one large body wound twice daily, which is exactly why I steer owners with big or frequent wounds toward cheaper bulk options.
The active ingredient sits at about 0.012% hypochlorous acid, no antibiotics, no steroids. There is no rinse step, which saved me real time on fidgety patients. And there was zero coat staining, so unlike colored sprays, I could always see the wound clearly. For competition horses, note the label lists no withdrawal time, but I still tell clients to clear any topical with their governing body and treating vet before a show.
For more first aid context, see our related guides on horse health. And for any wound that worries you, the AAEP wound guidance is a sensible owner reference before you call your vet.
How this product has changed
Vetericyn has run this hypochlorous acid platform across its equine and small-animal lines for years, and the equine spray formula has stayed consistent through my use of it, which I count as a plus for a product I want to trust in a pinch. The 16 oz trigger bottle is the size I reach for most, with an 8 oz option for smaller kits.
I have not seen any FDA recall affecting this product line during my testing window, but I always check current advisories before restocking and recommend you do the same for anything you put on a wound. If the formula or labeling changes in a way that affects how I would advise you, I will update this review and note it here.
My bottom line has not changed since week one. This is a gentle, practical, sting-free cleaner that belongs in most barn first-aid kits for minor wounds and skin care. It is not a vet, it is not a cure, and it is not the cheapest way to flush a big wound. Used for what it is, it is a quiet, reliable workhorse.
