Going into a bit more detail, I've dealt mostly with using the various markers for panel lining on bare plastic. With most water based acrylic markers, I've had the most success removing excess panel lining with a precision cotton swab (like these ) and a little rubbing. Typically the alcohol was reserved for the most stubborn stains. I'll also use the knock eraser on larger, flatter surfaces, or where I can on staining. It also helps with removing marks from the occasional slip of the hand.
