This video is about how I clean and lubricate loop end, and hole end, clock mainsprings using a mainspring winder and its accessories. This also explains how to remove and reinstall hole end mainsprings to their barrels.

NOTE: Usually, with all mainsprings, you would clean them at the same time you're cleaning the other parts of the movement (like in an ultrasonic cleaner).

Please excuse the fact that this video ran a bit longer than I had originally hoped due to an unknown, horrible prior "repair" to a mainspring (not by me!).

Take care, everyone, and please like and subscribe!
