That is what I use as well. What I do is first wash the bird with dish soap, then rinse. I then soap it up again with dish soap again and then add a couple of drops of the vetrolin to my hands and rub my hands together getting a good lather. I then apply to crest, beard, and tail. Then you can start lathering the bird all over. It may take a couple more times of adding the drops to your hands, lathering, and applying. You don't want to put this bluing shampoo directly on the bird. Use some sort of shampoo/dish soap first to dilute the vetrolin. If you even get a drop of it directly on the bird it will stain so quickly dilute it. It is a balancing act, but it works very well once you get the hang of it. You can apply it to the foot feathers directly, just not the silkied feathers.
