How to keep finches groomed
Gently mist your finches with a water bottle every day.
This will mimic a light rainstorm, dampen the birds' feathers, and allow them to better groom, clean, and straighten the plumage. Do not spray the finches directly in the face.
Instead, set the water bottle nozzle on the " mist " or " spray " setting, and gently mist the finches from outside the top of their cage. Set aside a specific water bottle that you use only for this purpose.
