Instructions
Unscrew the phone from its exterior. Examine the exterior and the inner workings of the phone to find the name of the manufacturer and phone model. Put the exterior aside.
Separate the phone into its parts. If you are not familiar with all the parts of your antique phone, you can look up the phone's model and manufacturer online to get a detailed plan for the phone's construction. Label each part and put it into a separate container.
Fill an empty container with a combination of dish soap and warm water. Take three to five parts of the phone and soak them for 15 minutes at a time. Remove these parts, put them on a towel, and allow them to dry completely. Repeat the process until you have soaked all of the phone's parts.
Clean all metal parts of the phone such as gears with rubbing alcohol or vinegar. Scrub down the phone's base, receiver, cords, and any other part that needs cleaning.
Wash the phone's exterior with a damp rag dipped in dish soap and warm water. If there is dirt encrusted within the phone shell, use cotton swabs dipped in dish soap and water to scrub it off.
Polish the phone exterior using a clean rag and polish appropriate for the exterior's surface. Use the diagrams you found online to help you put the phone back together.
Send the phone to a professional phone converter to restore its ring and render it usable.
