Keep moisture out
Keeping moisture out is the best way to prevent electrical corrosion. Water is usually the culprit behind electrical corrosion, so keeping it away from your electrical panel and indoor and outdoor connections is crucial. Regular inspections can help identify any signs of water intrusion, such as leaks or cracks in indoor walls and foundations or water collection around outdoor wiring.
To keep moisture out, start by checking for any damaged pipes or leaks indoors. Even small leaks can cause significant corrosion over time. Be vigilant in inspecting areas prone to moisture, such as basements or areas with plumbing fixtures. Address any leaks promptly by repairing or replacing the affected pipes.
Additionally, ensure proper ventilation in areas with high humidity, such as kitchens and bathrooms. Use exhaust fans or dehumidifiers to reduce moisture levels and prevent condensation on electrical components.
For outdoor wiring, ensure that water from gardens or rain cannot collect near the electrical connections. Inspect the area regularly and make necessary adjustments, such as re-routing wiring or providing adequate drainage to prevent water accumulation.
If you live in an area with high humidity or are concerned about moisture levels, consider using electrical contact cleaner. These precision aerosol sprays are designed to dissolve and remove dirt, oil, and oxidation build-up from electrical components and contacts. They can be easily purchased at most home or hardware stores.
Finally, consider using dialectic grease, which creates a protective barrier around wiring, preventing moisture accumulation and corrosion. This grease is especially useful in environments with high humidity or where water intrusion is challenging to control. It is essential to clean the area before applying the grease and ensure that all surfaces are cool to achieve the best results.

Regular inspections
Identify High-Risk Areas
Not all electrical contacts are equally susceptible to corrosion. Outdoor wiring, for instance, is more vulnerable to the elements, increasing the likelihood of corrosion. Similarly, areas like the garage and outdoor lighting are at higher risk. Pay close attention to these areas during your inspections.
Visual Inspection Checklist
When inspecting your electrical contacts and wiring, there are several key indicators of potential corrosion to watch out for:
- Water or moisture accumulation near wiring or electrical panels.
- Damage to pipes, foundations, or walls that could lead to water ingress.
- Signs of deterioration, rust, or oxidation on electrical components.
- Discolouration or surface corrosion, which could indicate salt spray exposure.
Timing of Inspections
The adage "prevention is better than cure" rings true when dealing with electrical contact corrosion. Regular inspections should be conducted proactively, not reactively. While there is no one-size-fits-all frequency for inspections, it is advisable to perform them at regular intervals. Consider setting a recurring schedule, such as monthly or quarterly checks, to ensure you catch potential issues early.
Cleaning and Maintenance
During your inspections, if you notice any dirt, dust, or signs of corrosion, it's important to take appropriate cleaning and maintenance actions. This could involve using a mild solvent like WD-40 and a soft-bristled toothbrush to carefully clean electrical connections. Avoid using wire brushes, as they can cause scratches and damage to delicate electrical contacts.
Additionally, consider using electrical contact cleaner, an aerosol spray designed to dissolve and remove dirt, oil, and oxidation from electrical components. This product is typically available at hardware stores and can help you effectively clean hard-to-reach areas.
By incorporating these practices into your regular inspections, you can significantly reduce the risk of electrical contact corrosion and maintain the integrity of your electrical systems. Remember, a proactive approach is the best defence against corrosion and its potential consequences.

Use dialectic grease
Dielectric grease is a viscous, non-conductive, waterproof substance used to protect electrical connections from corrosion and dirt. It is a popular product used in garages across the country, although it is not an automotive necessity. It is often applied to spark plug boots, lightbulbs, and battery terminals.
Dielectric grease is a lubricant that can be used to seal gaps and prevent corrosion by sealing out moisture from electrical connections. It can be used on circuit breakers, ignition coil connectors, plastic or rubber parts, fasteners, and O-rings. It is also useful for preventing arcing and the leaking of current in the presence of moisture.
Before applying dielectric grease, it is important to clean the area with an electrical contact cleaner. This will remove any dirt, oil, and oxidation build-up from electrical components and contacts. Once the area is clean and dry, simply squeeze out the dielectric grease and apply an even coat to the electrical connections and contacts.
Dielectric grease can also be used to prevent corrosion on battery terminals. A coating of dielectric grease can be applied to the tops of battery terminals to protect them from corrosion and rust. This can help to prevent the battery terminals from seizing to the battery posts and can also protect the retaining hardware from corrosion.

Avoid wire brushes
When it comes to preventing electrical corrosion, it's important to avoid using wire brushes for cleaning electrical contacts. Here's why this is crucial and what alternative methods you can use to effectively clean and protect your electrical connections:
The Dangers of Wire Brushes
- Most electrical contacts are made of copper, or copper plated with tin or silver. These materials are softer than steel, which is what wire brushes are typically made of.
- Using a wire brush on these soft metals can cause scratches and damage to the electrical contacts. This is due to the harsh abrasion of the stiff steel wires on the surface of the contacts.
Alternative Cleaning Methods
- Instead of a wire brush, opt for a softer, less abrasive tool like a clean toothbrush. This will help you reach tight spaces without causing scratches.
- Use a mild solvent like WD-40, which is safe for copper, tin, and silver. It effectively removes corrosion and other deposits without causing harm to the metals.
Reducing Surface Variations
- The goal when cleaning electrical contacts is to reduce surface variations at the point of contact between conductors. Scratches and pockets at the point of contact reduce the surface area, affecting conductivity and potentially leading to corrosion.
- By avoiding wire brushes and using softer tools and mild solvents, you minimize the risk of creating scratches and surface irregularities.
Protecting Electrical Connections
- After cleaning, you can further protect electrical connections by applying dielectric grease. This seals and lubricates the connections, preventing moisture intrusion and corrosion.
- Regular inspections of your wiring and electrical panel are crucial. Check for any signs of deterioration, rust, or oxidation, especially in areas exposed to the elements, like outdoor lighting and garages.
By avoiding wire brushes, using gentle cleaning tools and appropriate solvents, and regularly inspecting and protecting your electrical connections, you can effectively prevent electrical corrosion and ensure the safe and efficient functioning of your electrical systems.
