Space-saver Tray Q? Or just high chair tray in general...

So, I often cut up her food on her tray, obviously with a sharp knife. It's has cut into the plastic of the tray. Over time, even after washing the tray after each meal, the cut areas have been stained by (I assume) tomato sauce, similar to the staining of Tupperware by that same type of thing. What is the best way to get the stain out? Totally random question, I know, but it has been bugging me forever!

Have you tried a magic eraser? If that doesn't work, try putting dishwasher gel directly on  the marks...let it sit for 5 minutes and then rinse it off. The dishwasher gel is the only thing that gets stains out of my white kitchen sink!
