Why and How to use Dielectric Grease

Dielectric grease is an effective barrier to moisture and protects electrical connections, ignition parts and wiring from moisture, salt, dirt and corrosion.
A major manufacturer of automotive sealants suggests a four-step process to protecting spark plug boots, connectors and battery terminals.

To protect spark plug boots:

1. Ensure the ignition system is off;
2. Remove heavy grease with a clean cloth;
3. Coat the inside of spark plug boot and the ceramic portion of spark plug with a thin layer of Dielectric grease.
4. Finally, snap the boot onto the spark plug, making sure the fit is tight.

For connectors and battery terminals:

1. Ensure the ignition system is off;
2. Clean the surface with a good battery cleaner;
3. Coat both parts of the terminal contact with Dielectric grease;
4. Reassemble, maintaining metal-to-metal contact.
