chip: inside the doors is usually the last place I wipe down 'cause it gets really dirty & grimy, especially the bottom of door where the drains are.
One wipe with a soapy mitt that you use for your wheels, then wipe down with a rinsed mitt, dry with a MF towel that's not one of your best (Wal-Mart quality towel is good here) 'cause you may get some grime and/or grease from the hinge side of the door.
I AIO everything I can reach on the door hinge side, the striker plate side, and the bottom, then I FMJ the same surfaces. Use your favorite sealant.
I find AIO/FMJ much easier to use than wax 'cause you don't want to plug the water drains in the doors with blobs of wax.
I've seen car show prepped cars that have been absolutely filthy under the doors 'cause you can't see this area unless you're laying on you back.
Living in the NorthEast & dealing with snow, ice, and salt I think it's important to pay attention to the door jamb area.
