Please avoid attempting to repair your clock on your own.

If your clock stops and you spray it with oil to make it go again, the movement will wear badly, because dust will stick to the oil. This then will form an abrasive paste which cuts through brass and steel parts. Shortcuts like cleaning the movement whole, even using an ultrasonic cleaner, cannot properly clean pivots, pivot holes, and mainsprings, and often promotes rust. These techniques merely postpone the need for a proper overhaul.

“It probably just needs to be cleaned.”

A clock movement must be taken apart to be cleaned properly. While it is apart it makes sense to do the necessary repair work as well. I see almost no clocks that have been so well maintained that they need only cleaning.

“My clock is wound too tight.”

Call us for an appointment for repair. It is time for the clock to be overhauled. The oil has dried up and there may be wear and damage as well.

“I sprayed some WD-40 on it and it worked fine for a while.”

This miracle stuff works fine on cars, but it will gum up a clock and cause excessive wear. This is the worst thing you can do to a clock.
