I'd soak with the ES first making sure he doesn't drink any, then dry his feet and apply the colorless iodine top and bottom, I used a q tip because I could get it spread better than that dabber thing that comes in the bottle. Read the post Amiga gave you it will tell you how often to apply it I believe it is every three days, let us know how it looks.So I just put him in Epsom salt again or do I just put the colorless iodine
