Thank you for your question regarding the LA59 door chime. Unfortunately there are no parts available for this unit any longer. To clean the plungers, remove the unit from the wall. On the back of the unit there are 4 caps for the plunger/solenoid assemblies. Remove the cap to remove the plunger and spring assembly. Use rubbing alcohol to clean the plungers, springs and solenoids. Allow to air dry before reinstalling into the unit. If you need any further assistance, please contact Technical Support at 1-888-336-6151.
