WD40 Contact Cleaner - 400ml 44376

Fast Drying Contact Cleaner is a non-conductive, precision spray designed for safe use on sensitive electrical components. It delivers powerful cleaning performance, easily removing dirt, dust, moisture, condensation, and flux residue from delicate electronics with minimal effort.

Simply apply the cleaner and allow it to dry completely before restoring power. It’s ideal for use on circuit boards, switches, spark plugs, tape heads, and other electronic contacts—eliminating the contaminants that can lead to current leakage and component failure.

In damp or humid environments, it helps displace moisture and improve electrical conductivity, making it especially effective for automotive applications like spark plugs and electrical connectors.

Formulated for safe use on plastic, rubber, and metal surfaces, this cleaner offers versatility and peace of mind across a wide range of tasks.

Equipped with the Smart Straw applicator, it provides two spray options: use the precision straw for targeted areas, or flip it down for wide-area coverage. Thanks to the 360° valve, you can spray at any angle—even upside down—for maximum ease and control.
