Yes, all receptacles that were sprayed with WD-40, especially the GFCIs, should be replaced. Here's why: Flammability

WD-40 is flammable and can create a fire hazard if it ignites inside a receptacle. While the risk might be low, it's not worth the potential danger.

Residue and Conductivity

WD-40 leaves a residue that can attract dust and debris. This residue, combined with the conductive nature of the WD-40 itself when wet, can create a conductive path between terminals. This can lead to short circuits, ground faults, or erratic operation.

GFCI Malfunction

WD-40 can interfere with the sensitive electronics inside GFCIs, causing them to malfunction. GFCIs are designed to detect tiny differences in current between the hot and neutral wires. WD-40 residue can disrupt this balance, leading to nuisance tripping or, more dangerously, a failure to trip when a ground fault occurs.

Damage to Plastics/Materials

WD-40 can degrade some plastics and rubber components within the receptacles over time, further compromising their integrity.

Cost vs. Risk

The cost of replacing receptacles is relatively low compared to the potential cost of a fire, electrocution, or property damage.

Warranty Void

Using WD-40 inside the receptacle may void the warranty.

What to do


Turn off the power

Immediately turn off the circuit breakers supplying power to the affected receptacles.2.

Replace all affected receptacles

Remove each receptacle that was sprayed with WD-40 and replace it with a new, properly rated receptacle. Use the correct type of receptacle (standard or GFCI) for each location.3.

Inspect wiring

While the receptacles are removed, inspect the wiring for any signs of damage, corrosion, or WD-40 contamination. Clean or replace damaged wiring as necessary.4.

Test

After replacing the receptacles and restoring power, test the operation of each receptacle, especially the GFCIs, to ensure they are working correctly. Use a GFCI tester to confirm that the GFCIs trip when a ground fault is simulated.5.

Inform Maintenance

Clearly communicate the issue to the maintenance personnel who sprayed the WD-40 and explain why it was the wrong approach. Provide guidance on appropriate cleaning and maintenance procedures for electrical equipment.

Important Safety Notes



Qualified Electrician

This work should ideally be performed by a qualified and licensed electrician.

Proper Tools

Use insulated tools designed for electrical work.

Lockout/Tagout

Follow proper lockout/tagout procedures to ensure the circuit remains de-energized while you're working.

Building Codes: Ensure all replacements and installations comply with local electrical codes and regulations.In summary, replacing all receptacles sprayed with WD-40 is the safest and most prudent course of action to prevent potential hazards and ensure the reliable operation of the electrical system.
