Each burner is held down with one screw. Remove it and the burner and tube can be removed.
Cleaning the plate is another matter. I scrubbed it with soap and water, then dried it. If you leave water on it it will rust (more than it already has). I ended up using Nevr-Dull to protect the plate further. It takes a while before the oil smell goes away, though.
If the burner ignitors are weak, you may want to have some of those parts on hand.
