Turn the mantle clock around, and open up the back. examine the gears, bushings and pivots. Check to see if the movement and other parts are working efficiently. If not, purchase cleaning solution from a clock supply store. Dismantle the movement and clean it using the clock cleaning solution and a small bristle brush. Polish the pivots with a dry cloth. clean the grime between the pivot and the hole of the plate on the movement with the brush. Remove old oil from the gears with the brush and use clock oil to re-lubricate. apply a few small drops at a time.make sure the mainspring or suspension spring is functioning. These springs are what make the movement and other parts of an antique mantle clock work properly. Replace a spring if broken. After replacing, check to see that the movement is restored. Make sure that the movement is aligned into the proper grooves within the clock when readjusted. If the spring is repaired, then the movement will function efficiently.Do not move the clock once the pendulum bob is attached in its proper position.
