How to Clean the Inside of a Mantel Clock

Access

• Most mantel clocks have a rear plate at the back which must be removed to access interior areas. The rear plate is usually held in place by tiny screws which can be removed with a suitably sized screwdriver. The sensitive components, such as the floating balance and the plastic gear levers, can then be taken out for individual cleaning.

Clock Unit Cleaning

• Rubbing alcohol is an effective liquid for cleaning the interiors of mantel clocks and their components. The clock unit itself can be dipped in a concentrated mixture to remove dirty residues. For more thorough cleaning, dilute the alcohol with an equal measure of water and leave the clock immersed for around 20 minutes. A heavily diluted cleaning solution however, should be used when cleaning mantel clocks with a clear coat covering. Clear coats are applied to keep mantel clocks looking bright but can peel away when immersed in strong concentrations of rubbing alcohol.

Component Cleaning

• The pivots of mantel clocks can be cleaned of dirt and debris with a small brush or toothbrush dipped in rubbing alcohol. Unwind the clock springs using a coil unwinder and brush all around their lengths. The wheels, pinions and any areas of the clock’s interior where dirt is present can be cleaned using the toothbrush bristles. Avoid immersing the clock’s components in the alcohol solution as this may cause them to degrade. Use a brush dipped in the solution instead.

Finishing Work

• Alcohol can degrade mantel clocks if left on for prolonged periods, so should be removed immediately after cleaning. Soaking the mantel clock in warm water for around 20 minutes neutralizes trace levels of alcohol which may still remain in the pores of the metal. A hair dryer set at a low level can be used to remove trace levels of moisture from the mantel clock and its components. Placing the clock in an oven pre-heated to 180 degrees Fahrenheit for around 20 minutes should remove any lingering moisture not removed through blow drying.
