How to Clean a Car Speedometer's Plastic Face
The plastic face of a car speedometer tends to get dirty as the car ages. As a result, it becomes harder to see what your current speed is, making you more likely to be stopped by for speeding or possibly even get in an accident. You can clean the speedometer's face, though, so you are able to clearly see your speed.

Tips & Warnings
Consider spraying the ammonia on the paper towels as well as the speedometer face.
Do not try to remove the plastic face and work on the actual speedometer part. These parts are made with precision and should only be cleaned by a mechanic or authorized technician.
Work in an open-air area. Cleaning with ammonia with the windows down can be hazardous to your health.
