What are those marks around the door on EZY 737 JW

They are the remains of the security seals that are used when an aircraft is left unattended. When removed they leave a mark that is a b***er to get off. Most aircraft will have them to some extent but that really is a build up.

The first Ryanair 737 has a mark level with the door handle and the first Easybus has one level with the window and one about a third up the door.
