Hoofmaster for anything to do with feet - purple iodine spray from tackshops for small cuts and abrasions on the body.
Watch out though with hoofnaster - not only do you get smiley faces, but purple jodhs and face too if your aim isn't too good. (Yes, he moved, I missed and ended up going to the shops with a purple cheek)
I used to use Purple Spray but have converted to a mixture of Tea Tree Oil and water made up in a spray bottle now....one bottle of TT last quite a while, does the same job, not as messy and smells lovely!
Love using TT as i find it so useful as part of a first aid kit for a host of other ailments too!
