How to care for a parakeet?

I have a parakeet and she preens all the time. I have sprayed her with mite and lice spray and I have a mite/lice can hanging on her cage. I clean her cage twice a week and keep her water dish full of clean water. Am I caring for my parakeet correctly? What else can I do to keep her clean…oh, she does enjoy bathing in my bathroom sink under a trickle of running water. Any help would be greatly appreciated.

How do I care for my very sick parakeet until I can get her to a vet in the morning?

I made her a warm nest at the bottom of the cage next to a water dish
thanks to everyone for answering but my bird died before I was able to get to a vet becasue it showed signs of being sick at night and by morning she had died. I found out the cause was from fumes from a non stick pan
