Purple stain on white painted surface.
The stains are the result of using an indelible marker (Marks-a-lot, Sharpie, etc.) on a wet surface(Why explained below). Some/most of the ink goes into the moisture and then will drip onto the table. Even if you can get at it immediately, it leaves a purple stain that bleach will barely touch and we don't want to repaint all the time.
Gleaners is a nonprofit organization that collects food, mainly from stores and redistributes it. One of the requirements is that the bar code on all product be crossed off. (Because that's the way we have always done it.)
Milk and other products that come in cold have water condense on them and even trying to dry them is a wasted effort and they have to go into a cold room as soon as possible.
The result is marking a wet surface which does not take the mark and it drips onto the white counter top.
