My 8X10 trays were looking a little grungy, so I ran them through the dishwasher to clean them up. The developer tray still had the gray/black stains on it after the trip through the dishwasher. My better half said to try a Mr. Clean Magic Eraser on the tray and it lifted the stains right off! No rubbing! The stains just wiped off.
