Yep, plenty of threads on cleaning atties, also YouTube is your best friend for that kind if stuff. A lot of people sell atomizer cleaner, but from experience, boiling water and alcohol seem to do a good job. If the attie becomes to stiff out completely stops firing throw it away. I recommend trying one of the smaller rebuildable atties. With a little wick and wire you can have a great attie setup indefinitely.
