Have you noticed a strange green substance oozing from your light switches or power points? This weird green goo is more common than you might think, and while it looks concerning, there's a logical electrical explanation behind it.
What Exactly Is This Green Goo?
The green substance leaking from your electrical switches and outlets isn't actually "goo" in the traditional sense. It's a byproduct of a chemical reaction occurring within your electrical installation. Specifically, it's copper corrosion mixed with plasticiser oils from the insulation materials in your wiring.
When copper wiring corrodes, it produces copper oxide and copper carbonate, which have that distinctive colour. When this corrosion combines with the oils leaching from deteriorating cable insulation, you get that sticky, green substance that appears to "leak" from switches, power points, and switchboards.
Why Does This Happen?
Several factors can contribute to this issue, but the most common reasons include:
Age of the wiring: Older electrical installations, particularly homes built between the 1960s - 1980s are more susceptible to this problem. The insulation materials used during this period are now breaking down after decades of use.
Heat: Electrical connections generate heat, and excessive heat accelerates the deterioration of insulation and promotes copper corrosion.
Moisture: Humidity and moisture exposure can speed up the corrosion process significantly.
Poor connections: Loose or faulty connections create resistance, which generates more heat, creating a vicious cycle of deterioration.
Overloading: Circuits that are regularly overloaded run hotter, accelerating insulation breakdown.
Is Green Goo Dangerous?
Yes, this is definitely a concern that requires professional attention. The presence of green goo indicates that:
Your wiring insulation is deteriorating
Copper conductors are corroding
Electrical connections may be compromised
There's an increased risk of electrical faults, short circuits, or even fire
This is not something to ignore or attempt to clean up yourself. While the goo itself isn't immediately hazardous to touch, the underlying electrical problems it represents are serious safety issues.
What Should You Do?
If you discover green goo leaking from your light switches, power points, or switchboard, don't call ghostbusters, take these steps:
Don't touch it! If you do get any on your hands, wash them thoroughly. Don't touch your eyes or it will hurt!
ignore it: This problem won't resolve itself and will only worsen over time.
Avoid DIY fixes: This isn't a situation for cleaning products or quick patches. The issue is within your electrical system.
Contact a licensed electrician immediately: A qualified professional needs to inspect your electrical installation, identify the extent of the problem, and recommend appropriate solutions.
Consider a full electrical inspection: If you have green goo appearing in one location, there's a good chance other areas of your wiring system may be similarly affected.
The Solution: Rewiring
In most cases, the permanent solution involves replacing the affected wiring and components. While this might seem like a significant expense, it's an essential investment in your home's safety. Modern wiring uses improved insulation materials that don't have the same degradation issues as older cables.
Don't Let It Slide
Green goo from electrical fixtures is your home's way of telling you that there's a problem that needs attention. While it might seem like a minor curiosity, it's actually an important warning sign of potentially dangerous electrical deterioration. The good news? Once identified and properly repaired by a licensed electrician, you can have peace of mind knowing your electrical system is safe and reliable.
