I always have this product on hand! It tackles the toughest stuff. I have been able to remove marker, halloween hair dye, food and wine stains, koolaid stains from the counter top. The possibilities are endless. One caution to this product, it is powerful so you might want to stay away from painter or stained surfaces. It could remove it and damage the surface. Stick to things like countertops, bathtubs, sinks etc. You can remove crayon and marker from wall surfaces pretty quickly so it usually does not affect the paint but I have had to so some touch ups a couple of times, especially on darker wall colors.
