Is it just the retractor that is bad or the emerg locking mechanism? I know in the past, not on a Mark unit mind you that I have just pulled them apart and cleaned them and at that point just lubed them again. After 15 years you can imagine all the dust and dirt that has been collected and that tends to mess things up. For the actual belt strapping, lay them out in the dishwasher and run them through a cycle but not the dry, they come out awesome and they do not make any noise. You can bag anything you do not want getting wet and after the dishwasher do the clean and lube portion.
