White doodle with "copper color stains" on beard and boy parts

[Dee Dee & "Bentley"]

My white doodle has cooper color stains on his beard and where ever he licks. Is there any product to prevent this. Using  shampoo to whiten his coat does not help for these areas..

Any help is appreciated.  He is in training to be a therapy dog so I'm thinking a cleaner look would be more appropriate.  .

I don't know hat keeps happening to my reply so here it is again:

I use a blueberry facial on my white doodle. Its made by Tropiclean. I have also heard that its better if they drink from a stainless steel bowl. Not sure why but thats what we have.

The only thing that I saw work was a mud pack from my neighbour's yard. Her white dog with stains was digging in the garden with a wet mouth. Later the dog was biting a sprinkler and the stains were 100% gone. I told her I was going to dig up her yard and sell it in jars. lol

Thank you for your suggestion. I've never heard of that product.  I looked on line and found many recommendations and sources to purchase from.  Will give it a try.  Thanks

I looked at my bottle and its actually called tear stain remover. I know the groomer uses blubbery facial so that is what I have been calling this. Daphne doesn't actually get tear stains. I just use this product on her mustache and beard.
