I use K9, great stuff. Been using it for years, before that the purple home made stuff. Same ingredients, but I suspect not as strong, this product does not stain.
This is great stuff, but warning do it outside as when they shake their head it will stain works well with yeasty ears, remember to shake the jar hard for a minute or two.
I used K9 ES a couple times and it worked great, they have not needed ear cleaning for months. Just used at the end of autumn when they had been swimming all the time and were getting moist waxy ears. For some reason my dogs hate it though. Their ears didn't look inflamed so I don't know why it should have stung. Probably will not ever get it in their ears again, sad since it works. Maybe try a small bottle first to see if they will put up with it.
