I imagine that the clutter you describe is coming from one of the principles of music theory. That principle is that any accidental lasts for the length of a bar, or a tied not across a barline, unless another accidental is added to the note.

So...

If a bar full of notation is a melody that goes

| g f# f e f f# f e | (for example),

and if you put a f# in, it will display with a natural on the 'f' notes that follow f#.
