WD-40 Specialist Contact Spray removes oil, dirt, flux, and oxidation residues from sensitive electrical or electronic devices. The product can be applied to electrical devices, contacts, plastics, and rubber. With the integrated spray head, you can switch between wide-area and precise spraying. The tube remains securely attached to the spray head, preventing it from being lost during use. For wide-area spraying, simply fold the spray tube down. With the tube extended, you can reach small gaps and apply the product accurately. The 360° valve allows the can to be held upright or upside down, making any application possible. Application: First, unplug all devices to avoid electrical supply and allow hot surfaces to cool down. Shake the can before use and spray from a distance of 15 to 20 cm directly onto the surface to be treated. This will remove any residues that could interfere with electrical contact. Tilt the surface while cleaning and allow any excess liquid to dry completely before restoring power. To avoid accidental damage, always check the manufacturer's instructions before applying the product to the device. Do not spray the product into cavities, openings, gaps, or areas of your device that do not have adequate airflow to support complete evaporation.
