Applying [None] character style

I have a script that finds text with a certain character style, cuts that text from the main story and anchors it in a frame that sits in the margin.

Everything works fine except that I'd like to have the option of removing the character style. However, when I apply the [None] character style InD shows [None] in the character style lists but the formatting for the character style that was just removed remains on the text.

Is there a way to have it work as if the [None] was manually selected from the character style list? i.e.: where the character style formatting is removed as well?

Thanks,

Ken
