I don’t know of any teacher who hasn’t stained work clothes themselves or had them stained as the result of a student mishap. I’ve stained enough neckties to create a drop-cloth. Coffee, ink, and markers seem to be the leading causes of those stains. Solutions to remove all those stains can be found on Stain Solutions.
