WD-40 Specialist Contact Cleaner Spray 11 oz 6-Pack — Fast-Drying, Residue-Free Electrical Cleaner

WD-40 Specialist Contact Cleaner Spray is a fast-drying, residue-free aerosol that lifts oil, flux, dirt and condensation from sensitive electrical contacts and circuit components.

Designed for technicians, hobbyists and maintenance pros, this 6-pack of 11 oz. cans delivers targeted cleaning power for switches, PCBs, battery terminals and control panels. The formula evaporates rapidly without leaving film, so cleaned contacts and delicate components return to service quickly. It’s engineered to remove common contaminants while remaining compatible with most metals, rubbers and many plastics when tested first.

How does this cleaner protect delicate electronics?

The rapid-evaporating solvent removes oils and residues that cause poor conductivity and intermittent faults without soaking components long-term. Because it leaves no residue, there’s minimal risk of attracting dust after cleaning.

• Quick drying to minimize downtime
• Residue-free formula avoids recontamination
• Pinpoint spray for controlled application

Where is it safe to use and what should I avoid?

It’s formulated for printed circuit boards, switches, connectors, battery terminals, relays and instrument contacts. Avoid using directly on adhesives, certain plastics, device touchscreens and keyboards unless you first test a small hidden area.

• Safe on most metals, many rubbers and many plastics when tested
• Not recommended for adhesive bonds or untreated display surfaces
• Test plastics before full application to confirm compatibility

How does WD-40 Specialist Contact Cleaner compare to other contact cleaners?

This product is engineered to remove more soil and flux residue than leading competitors while drying faster and leaving no film. The pinpoint spray and controlled formula make it especially good for targeted electrical maintenance and repair.

• Designed for superior soil removal vs. many market alternatives
• Leaves no conductive or insulating residue
• 50-state VOC compliant for wide regulatory acceptance

What application tips help get the best results?

Power down equipment when possible and work in a well-ventilated area. Use the straw for precision, allow solvent to evaporate fully before re-energizing, and repeat if visible residues remain.

• Always power off and discharge capacitors when practical
• Spray briefly from a short distance — avoid pooling
• Allow full evaporation before powering equipment back on
