My mare had BAD scratches 2 years ago…after trying MTG, Chlorhexidine, Desitin, even some concoction I got from the vet, I couldn’t get rid of them. She had no swelling up her leg, just in the pastern & scabby yuckiness. I finally tried Equifit Silver Clean Balm from SmartPak–not cheap, & the small tin only lasted 4 days-BUT, it worked & got rid of the scratches. Now I have a bottle of Equifit Silver Maint. Clean Wash on hand—& if she starts to get them, I just wash them with this for a day or so, & they don’t turn into anything more. It’s great on other cuts as well. I did use Desitin after the wash to keep it protected, & that seems to work well.
