How to get rid of White Tongue?

When I wake up in the morning I have awful morning breath and a terrible taste in my mouth. After I eat, drink, and brush my teeth the taste/smell usually goes away however I still continue to have a white tongue. I use a tongue cleaner, I brush my tongue, and I use mouth wash however my tongue stays white. Is there any remedy that can fix this? I read that snorting saline solution could help because it kills bacteria in your nose/mouth but for some reason I feel that its not a fantastic idea.
