If the film is white-to-grayish in color and is a dry film then that is normal. If left on the glass it may even get a brownish tint to it. The white ash film actually indicates that you have a fairly efficient burn flame. If you get a black sooty film then your flame is too lazy and you will need to adjust air/fuel ratio.

There are tons of ways that people prefer to remove the film from the glass, but dampened paper towels work just fine.
 
The whiteish/tanish film indicates the fuel/air ratio is perfect... black means it's too sooty (probably a dirty stove or running on low too much)... a brownish film means you're running with too much air...
