You are doing a good job of keeping them clean. You can also put some generic diaper rash cream on the sores to help them heal faster and keep the flies off.
I don't show, so I can hack my poor horses legs up any way I feel like to keep Scratches at a minimum. I just shaved everyone's fetlock areas down, crewcut style, this morning. This is the third shaving this year and I have only had Scratches outbreaks right after it rains, the sun comes out and they walk thru the humid/wet grass.
I never used to cut leg hair but I do since I moved here because two of the four are a lot more prone to Scratches and Rainrot these days.
It's a good thing their fetlock hair isn't part of their breed standards because I shave it clear back to where one can see the Ergot
The purpose of shaving all that hair is to allow the skin to dry quicker; the hair holds moisture in and the begets scratches sores on horses prone to them.
The immune system plays an important role, as well. Like people, some horses naturally have a weaker immune system. My horse most prone to Scratches is also on herbs for dust/mold/pollen allergies. I feed him 2,400 I.U. of people Vitamin E daily, during the warm months, to help.
