What is the best thing to spray on electrical connections?

The best sprays for electrical connections are specialized contact cleaners from brands like WD-40 Specialist, CRC, or DeoxIT, as they are formulated to safely clean without leaving residue. For preventing future corrosion, consider using a silicone-based or dielectric grease, but ensure the product is labeled safe for electrical connections. For added protection, some manufacturers also offer a contact cleaner with a protective barrier formula.

Types of sprays

This video demonstrates how to use WD-40 Specialist Contact Cleaner to clean electrical components:

Contact Cleaners:
These are the primary sprays for cleaning. They are solvents designed to remove contaminants like dirt, dust, and oxidation from electrical contacts to restore conductivity.

Fast-drying formulas: These evaporate quickly and are often non-conductive, making them safe for sensitive components like circuit boards. Examples include WD-40 Specialist Electrical Parts Cleaner and CRC QD Electronic Cleaner.

Anti-corrosion formulas: Some contact cleaners are specifically designed to remove existing corrosion and leave behind a protective barrier to prevent future issues. DeoxIT D5S-6 is an example of a popular choice.
Dielectric Greases / Anti-Corrosive Sprays:
These are used to protect connections from moisture and corrosion, especially in harsh environments like automotive or marine applications.

Silicone-based: Often used in automotive applications to prevent corrosion on electrical connections.

Specialized anti-corrosives: Products specifically labeled as safe for electrical connections, such as some found in marine supply stores, can provide a more heavy-duty level of protection.

Determine your goal:
If you have dirty or oxidized connections, use a contact cleaner. If you want to prevent future corrosion, use a dielectric grease or anti-corrosive spray.
Check compatibility:
Always check the product label to ensure it is safe for the specific type of electrical connection you are cleaning or protecting.
Consider the environment:
For connections exposed to water, use a spray specifically designed for that environment, such as a marine-grade anti-corrosive or a fast-drying contact cleaner.
Opt for residue-free formulas:
Choose products that are labeled as fast-drying and residue-free to avoid leaving any film behind that could interfere with the connection.

Is it okay to put dielectric grease on electrical connections?

Yes, it is okay to use dielectric grease on electrical connections, but not on the contact surfaces. Its purpose is to protect against corrosion, moisture, and dirt by applying it to the outside of the connection, not between the metal parts that conduct electricity. Applying it correctly involves a thin coat to the metal after the connection is made, or packing it into the back of connectors to seal them from the elements.

How to use it correctly

Apply to the outside:
Place the grease on the outer portions of the connector or on the part that will be exposed to the elements, such as battery terminals, spark plug boots, and the back of plugs.
Allow for metal-to-metal contact:
When the connector is joined, the pressure should push the grease away from the metal-to-metal contact points, allowing for proper electrical flow.
Use sparingly:
A thin coat is usually sufficient.
Use on terminals, not contacts:
Don't put grease on the actual surfaces where the electricity needs to make a connection; this can create a poor or failed connection.
