You might want to try Ept-Otic to clean her ears. You can get it from your vet. It's similar to the stuff humans use for swimmer's ear. You poor a little into the ear canal, rub the outside of the ear to work it in, let your dog shake her head and then use a cotton ball to wipe away the excess. If you're having ear problems do it once a week for a month or two. Eventually it'll get all the build-up out and back to normal.
