A few treatments I have tried, all worked with varying success:
- Yellow Listerine, full strength or 50/50 diluted. Saturate the area daily, do not rinse out.
- Apple Cider Vinegar, full strength (REAL ACV, not just apple flavored white vinegar). Saturate the area daily, do not rinse.
- Aloe Advantage Wound Cleanser with Phenol. Saturate daily, do not rinse. This has an analgesic (pain killer) in it, so it's especially good for horses who are sore because of the rain rot.
Equine Wound Care
- Wound-Kote or Blue Lotion. Spray affected areas thoroughly every other day, or after riding (if you brushed out the spray from the day before). My husband likes this treatment best, lol. Your horse will look blue polkadotted, but it works!

You also need to be improving his skin from the INSIDE! A healthy horse is less likely to get rain rot and will fight it off more easily. Put him on a hoof & coat supplement that is high in Omega 3's, like Glanzen3
, Omega Horseshine
, or Smart Pak's SmartHoof Ultra
I would also add some unfiltered Apple Cider Vinegar to his diet. That will help get his skin PH back to normal and kill an infection or fungus that has gotten under his skin. Start with just a splash in his food and work your way up to 1 cup a day. Some horses don't like the taste, which is why you should start with a small amount.
Once the rain rot is 100% gone, you can discontinue the use of the ACV in his food, though I would continue with the hoof/coat supplement but in a half dose.
Also, if you're blanketing him, you need to buy a second blanket and keep them washed. Between washings, Lysol the HECK out of it every couple of days.
Same for saddle pads. Keep them washed and always use a clean one on him. You can reinfect him with a dirty pad or horse blanket.
Make sure you keep your grooming tools separated. Do NOT use them or the saddle pads on any other horses. Dunk your brushes and curries in a 10% bleach solution after every use, so you don't reinfect him or accidentally spread it to other horses.
