Best method to removing stains

This show season we have a calf that has more white and more hair than any other calf we have had in the past.  My question to all you pros out there in this haired cattle world,  what can I use on their hair in the places of the quarters, lower legs and their chest floor to get the stains out? It bugs the tar out of me to see him all dirty (or the appearance of being dirty).  We wash every other day right now with a once a week shampooing.  Is there something else I should be doing daily, weekly, or monthly to keep the stains down to a minimum?  Any advice you all could give me will be greatly appreciated.  The more home - like remedies the better; however, not the only way for sure. 

woolite always took our stains right out

1- Keep the pen clean. We have a white one and the stalls are cleaned daily like picking horse stall.
2-Use Kleen sheen in your post rinse mixture. It coats the hair shaft and reples dirt and dust.
3- We use Oxy-Clean liquid spray and let it set. It britens spots pretty good.
4- Also use shimmer lights or purple shampoo when washing to keep white brite.

I have always been afraid of blue rinse. Afraid I will end up with a blue hair or green cast if the hair is really yellow.

We use lemon juice 15 min prior to washing. Spray it on heavy and scrub it in

You could try a bluing shampoo for cattle. I show shorthorns ( some tend to have lots of white which gets dirty easily). The bluing shampoo seems to work.
