Bye Bye Odor is a natural non-toxic microbial solution especially formulated to substantially reduce or eliminate the ammonia levels from animal urine as well as manure odors. Bye Bye Odor is different than other products on the market because it actually consumes the organics causing the smell and the ammonia. Other leading brands simply soak up urine for removal or try to capture the ammonia vapors.The microbes used in Bye Bye Odor are effective against manure, urine, perspiration and many other funky smells INCLUDING skunk. To use, simply pour 4 oz into a clean 2-3 gallon garden-type pump up sprayer and add tap water. Then, clean stalls as you normally do then spray a mist of Bye Bye Odor every day on the wet spots. Its quick and simple.
