Anyone know of a good whitening/stain removing shampoo that works? Or am I looking for unicorns here? For a smoke heifer that has some bad stains on her knees and flank. We've used Sullivan's Bright Lights and are currently using Vetrolin White n Bright. I prefer the Vetrolin to the Sullivan's as it foams up better and seems to spread out more while the Sullivan's just seemed to sit wherever I placed it and didn't "soap up" as I would like it. The soaps get her clean and remove a lot, but just don't seem to really truly get her back to the light smoke color that she is everywhere else. Also I was browsing Sullivan's website and saw their Stain Buster bluing shampoo. Anyone tried it? We're running a show tomorrow and a vendor will be there so I can pick up a bottle up to try. Thanks!
