I know that this is a non-answer, but the best thing you can do is to keep his face clean and dry and be patient until he is 1.
My Nikki had horrible tear stains when she was a puppy and it bothered me a lot. People actually said nasty things to me about her appearance. As if I could prevent them.
But now they are virtually gone. When she had them, we had a daily routine. We checked to make sure there were no hairs in her eyes, used a gentle eye wash, then washed the face and beard with Spa Lavish facial scrub, dried, and then combed cornstarch or baking soda through the hair to keep the area clean and dry, then we brushed her teeth.
We still do the same routine ever other day, even though there are no tear stains anymore. (We don't need the cornstarch/baking soda anymore)
Hope this helps.
