Description and Fields of Application
WD-40 Specialist Contact Cleaner is a technical cleaner specifically formulated to quickly and safely dissolve stubborn contaminants on electrical or electronic devices and circuits. Its non-conductive formula with very high evaporation speed allows for safe cleaning of sensitive instruments, restoring proper electrical conductivity without the need for scrubbing or rinsing. It is the ideal product for cleaning printed circuit boards, switches, controls, printers, photocopiers, reader heads, meters, and complex electrical panels.
Exclusive Benefits
- Quick Drying and Residue-Free: Evaporates in just a few moments without leaving streaks or oily deposits that could attract dust or cause malfunctions.
- Safe Dielectric Insulation: The formula boasts excellent dielectric strength up to 33.8 kV, making it completely safe on all electrical and electronic equipment at rest.
- Dual Position Dispenser System: Allows you to choose between a wide-area, diffused application (with the straw down) and an ultra-precise, targeted application (with the straw up), perfect for reaching the tightest spaces or micro-components.
- NSF K2 Certification (No. 145372): Product registered and suitable for use as a solvent for cleaning instruments and electronic equipment in food processing or packaging contexts (without direct contact with food).
Material Compatibility and Safety
The detergent is formulated to be totally compatible and safe with:
- All types of metals (copper, brass, aluminum, steel, etc.).
- Plastic components and synthetic insulating materials.
- Rubber parts and elements present in the seals of the devices.
Instructions and Recommendations for Use
Follow the instructions below carefully to maximize the effectiveness of the product:
- Disconnection: Be sure to turn off the equipment and disconnect it from any electrical power source before applying the cleaner. Do not apply to hot or live circuits.
- Mixing: Shake the aerosol can vigorously before use to homogenize the active solvents.
- Application: Spray directly onto the area to be treated or onto the contacts to be cleaned, choosing the precision straw for difficult spots.
- Drying: Allow the product to dry completely. Evaporation time may vary depending on environmental conditions, but it is essential to wait for the solvent to evaporate completely before turning the equipment back on.
