Precision cleaning for electrical contact points, residue-free
WD-40 Specialist Fast Drying Contact Cleaner 400ml is a contact cleaner spray designed to clean sensitive electrical and electronic components from oil, dust, dirt, flux residue, and condensation. Its fast-drying formula helps remove contaminants that may impair electrical contact without leaving residue on the cleaned parts.
When you need to clean electronic circuit boards, plugs, or electrical connections, this product provides targeted cleaning for contact points and precision areas. It is a suitable choice for maintenance tasks that require a fast-evaporating electronics cleaner, not a lubricant spray that leaves a film on the surface.
What makes the WD-40 Specialist Contact Cleaner stand out?
Cleaning that helps restore better contact: Removes surface contaminants and condensation that may cause poor electrical conductivity, helping to address contact issues related to dirt; however, it does not repair damaged components or replace the need for fault diagnosis.
Fast drying, no residue: Suitable for tasks that require cleaning contact points without leaving deposits after the cleaner evaporates, with the necessity of waiting for complete drying before restarting.
Spray control and precise access: The Smart Straw technology allows switching between targeted spray using the straw and wide spray for covering larger areas, while the 360° valve helps use the can at various angles, including upside down.
Uses for contact cleaner spray
Suitable for cleaning contact points on printed circuit boards (PCBs), electrical switches, control units, and automotive electrical connectors. Its applications also include suitable electrical components inside printers and copiers, recording heads, and removing condensation from spark plugs and electrical connections, provided that the manufacturer's instructions for the device are followed.

Correct usage method
Disconnect all power sources and allow hot surfaces to cool. Ensure that all stored electrical energy is discharged according to the device maintenance procedures before working on it. Shake the can well, then spray onto the target part from a distance of 15–20 cm, tilting the surface to allow excess cleaner to drain. Allow it to dry completely and ensure the device is well ventilated before reconnecting the power.
Test the cleaner first on a small plastic area, and avoid screens, adhesives, and keyboards. Do not spray inside closed cavities that do not allow the product to evaporate completely, and always follow the device cleaning instructions.
Important Warning: Non-conductive does not mean it is safe to use while powered on. The product is highly flammable; use away from flames, sparks, and hot surfaces, with adequate ventilation and while wearing gloves and eye protection. Keep away from children and sunlight, and do not expose to temperatures exceeding 50°C.
FAQs about contact cleaner
Is this the regular WD-40?
No. This version is intended for cleaning electrical contact points without residue. The multi-purpose WD-40 is not a contact cleaner and leaves a lubricating and protective film on the surface.
Is it suitable for cleaning circuit boards and automotive plugs?
Yes, it can be used on suitable circuit boards and electrical connections, after disconnecting power and verifying material compatibility and the maintenance instructions for the device or vehicle.
Is it safe for all types of plastic?
It is not necessarily compatible with all types of plastic and coatings. Test first on a small area, and avoid screens, adhesives, and keyboards.
When can I turn on the device after cleaning?
After complete drying, draining of any excess liquid, and proper ventilation of the device. Do not rely on a fixed time in minutes rather than ensuring complete dryness.
