How does everyone deal with tear stains on yellows? Are there any tried and true remedies?

When our now 3.5 yr old yellow boy had some tearing, the breeder told us to simply wipe his face/below his eyes with a soft, damp cloth. Did the trick for us.

I have one yellow who gets tear stains, I give him angels eyes supplement, and he no longer has stains! I just put a sprinkle on his food maybe 2-3 times a week.

yes I do. I am a medical professional.

My older girls have tear staining also and I don't like it. A couple of questions for CD, being that he is a doctor. . .
Have you used Tylosin (Tylan Powder) instead of Angel Eyes? How much is a pinch? How long have you been using it?

Tylosin is the active ingredient in Angel eyes.

Desatin ointment

My vet prescribed 1/8th teaspoon of Tylan powder sprinkled on food twice a day. My guy is 7 years old and about 100 pounds.
