Asher has developed a pinkish scab above his hooves. Is it rain rot (I think it is)? What should I use to clear it? Antibacterial soap?

Bannix or yellow listenine(a much cheaper and effective option)
I used M-T-G on my horse when she had rain rot and it worked pretty good.
You can probably go to a local tack store and buy some rain rot stuff.
