A sticking doorbell chime is a nuisance, whether it refuses to ring properly or continues to chime long after the button is pressed. This may be caused by a mechanical problem, but could also be the result of accumulated dirt around the plungers or clappers. Try cleaning these parts thoroughly before attempting an expensive, time-consuming doorbell repair or replacement. The built-up dirt can be removed with little fuss, using a few items found in most households.

Remove the doorbell's cover to clean it effectively.

Step 1

Remove the screws from the doorbell cover. Place them in a safe location and carefully pull the cover off.

Step 2

Dip a cotton swab into rubbing alcohol. Make sure the cotton tip feels very moist.

Step 3

Rub the cotton swab over the clapper and gong, applying just enough pressure to remove dirt without damaging the unit.

Step 4

Replace the cotton swab as it becomes soiled.

Step 5

Use the same method to thoroughly clean the plungers of mechanical doorbells. Also clean the indented area that the plungers travel when in operation.

Step 6

Put the doorbell cover back on after cleaning is complete.
