BYE BYE ODOR 32 oz Concentrate by Spalding Laboratories

I have used this on rubber stall mats, on my horses wet spots. It works well at eliminating the ammonia smell, which helps with less flies in the summer. In the winter it is nice just not to smell so much ammonia. Healthier for our horses. I have also used it on an area of our cement floor that on old barn cat had started to urinate on. It has taken several applications, finding all the spots and then treating them (wetting it enough to soak into the cement and old stain) But it does work and we have almost entirely eliminated that smell as well. A few more searches and I feel we will have those odors gone too. I only gave it four stars because I feel for about $10 a gallon it is still a little pricey, for daily use. Seeing as you have to Wet/soak the urine spots you are treating, depending on the type of surface and how old the stain/odor is.

It seemed to temporarily reduce odor but never totally got rid of it. Used it on a dirt floor area of crawl space in an old home along with rock/concrete area. It is quite expensive and was hopeful it would eliminate odor, but for price I expected better results.

Works well and is much cheaper than Sweet PDZ that we used to use. We have 3 horses and they all have barn stalls, outside paddocks and an arena. When the horses are in the arena, we try to get them to pee outside if we can. We always spray the stalls, the paddocks, the arena and anywhere outside that the Horses pee and the smell is not noticeable to me (average odor sensitivity) and seems to work for my wife (very sensitive).

This product is used in my horse stalls to reduce odor. It works well in combination with stall cleaning at least 2x day. Will purchase again

I've used Bye Bye Odor for a fair amount of years now in my horse stall area. Still the same great stuff it's been right along. I have two horses that stay in their stalls during the daytime in the summer and this really takes care of the urine odor. One bottle does the job for just about a year. this is the best stuff I've found to do the job

We use this every night in our horses’ stalls. We much and sweep the wet spots, then spray. It really keeps the ammonia odor at bay. Great product. Not the cheapest, but works.

This stuff is expensive, but it really works. I keep two horses at home, and for about ten months of the year, they're on pasture - either grass or snow. However, for a month at the beginning and end of winter, I have to keep them off the pasture and confine them to the paddock/riding arena. When they are in the arena full time, of course they end up peeing there, and the odor can get overwhelming very fast. It makes caring for and riding them unpleasant, and the ammonia odors waft over to the house in warm temperatures. Eeew. I decided to try this product and it made a huge difference. I use it slightly more dilute than recommended, mixed in a 2-gallon pump-up yard sprayer. Every day, and at first twice a day, I give a good spray to any pee spots that I can see. The overwhelming ammonia odor was gone within days. In my eyes, it is totally worth the expense to avoid the smell, especially since I only use it for a small portion of the year. So, if you're looking to reduce the smell in your outdoor paddocks as well as your barn, this is the product for you.

If you have a barn, pets, or anything that smells, you need this product. Seriously. It eliminates weird mystery odors in the barn, ammonia smells in the horse's stalls, pet accidents in the house, and pretty much everything else. If this seems pricey, try out the pre-made spray or the 4oz concentration.
