Thus, it can be used in various settings like car repair facilities, in the home for electrical work, and wiring on recreational vehicles. Additionally, dielectric grease’s high insulation factor can protect traffic and street lights from rain and snow and can be used on boat electronics to protect them from the ocean and sea salt spray. The grease’s hydrophobic nature seals out water, so the circuit continues to work correctly.
It must be appropriately applied since it is often misconstrued as an electrical conductor (not an insulator). If too much is left on the surface, the flow of electricity could be hindered.
For instance, depending on how often you actually need to change your car’s spark plugs, you can put some on the ceramic portion of a plug, but if it gets on the metal terminal, it could obstruct the electrical connection. Applying it to the inside of the spark plug boot (while avoiding the electrical contact itself) will help keep the ignition coil spark from arcing around to ground.
Dielectric grease is cheap to buy and is available virtually everywhere. It’s ready to use out of the container and doesn’t require additional mixing with other ingredients. Last but not least, it can be easily removed with standard petroleum distillates.
