If wellness food is causing teary eye stain why not stop feeding them that brand of food?
Why use chemicals to try and combat the staining?

Doesn't make sense to me.

When I got my dog she was on a low grade purina puppy chow food. Her eyes were totally bad as well as other things.
I ditched that food immediately.
Here eyes started to clear.

I out my dog on a high quality kibble that was in the 28% protein range. I keep her in the 20's as far as protein content goes but also because I cook for her 50% in addition to 50% kibble.

We had a bit of an issue before Christmas. I took all of the higher glycemic foods out of her diet, that included yams, peas and carrots. I also put her on a low glycemic kibble; Go Natural Salmon Formula.
When I feed her cooked food I use two Cruciferous vegetables, portioned equally. Boiled, drained well and mashed. A good quality protein, chicken bot white and brown meat, turkey or beef, all boiled lightly but cooked through. Mince or grind. Add to vegies at a ratio of 25% veg 75% protein.
The Go natural Salmon formula kibble is mediocre in size. Some kibbles are very hard and concerns me so I do tend to moisten with some warm water.
We brush teeth daily so isn't really an issue. She does eat some kibble without any moistening.
Results are that there is barely any gunk in her eyes, her glands haven't been filling up and ... her coat is Way softer.
Overall a much happier girl.
No Chemicals, ever. Either filtered or distilled water, fresh daily.

I met a lady with a couple Maltese dogs once. She had a problem with staining. She began feeding a tsp of whole fat yogurt with active bacteria in the ingredients once a day and the stain cleared.

Please stop using chemicals on the dogs, especially around the eyes, It Is Not Necessary! Probably adds to the problem.

I battles the teary eye and the staining for the past couple years. (Only got my dog August 2008) and we do not have that problem any more. Bottom line here is Diet!
In fact I was using way too many vegetables in her diet before. When I cut them back and added more animal protein, the results were amazing! I also took her off of Roycal Canin 28 and is on Go Naturals Salmon Formula.

We have found paradise! Working like a charm, in more ways than one.
Sometimes, I will add a tsp of whole fat yogurt to her home cooked portion of her meal(s).

Shampoo I use is Vet's Best Oatmeal and Vanilla. Have used it since day one.
We sometimes use Tropiclean. Like twice.

If the food is causing problems, look at the ingredients. Likely there is sweet potato, peas, carrots, rice, wheat and corn in there! Don't feed kibble with those ingredients.
