Hi,
I just use PolarPure as a woundwash (regular iodine would also be fine) and coat the wound with instant mashed potatoes powder.
This will give you in instant "scab". You could then cover with gauze if needed but I don't.
Expect the potato powder to turn purple when it contacts the iodine. Don't know why this happens, it just does.
Works for me.
