2001 Jaguar XK8 - Rear Wheel Speed Sensor - Remove, Clean, Reinstall + more 

Hi Nathan, I first wiped it with a regular "wet wipe" (unscented baby wet wipe) to take off the majority of the dirt. After that I literally took the sensor to the sink and washed it with water and dish soap. The sensor is sealed and protected, as it is designed to be exposed to the elements, so no danger in washing it in the sink. You may want to protect the electrical connection area, but other than that - water all over the sensor is fine.
