Very nice truck Lynda!
You can remove the painted logos from the rear mud flaps with a rag and some acetone or nail polish remover. Just be careful not to spill it on anything else, as it damages rubber,plastic and obviously paint. It will remove any coating on the metal part of the flap too, so be sure to wipe it clean, and I would put some carnuba wax on the metal portion to keep it from corroding.
