WD-40 – Specialist Contact Cleaner – Technical Data Sheet

Use case
Residue‑free cleaning of contacts, switches and PCB assemblies to restore conductivity and reduce leakage paths.

Advantages

• Low residue, fast drying and precision jet control.
• Removes films that cause micro‑arcing and poor signals.
• Helps with intermittent faults due to contamination.

Application

• De‑energize where possible; avoid live arcing.
• Short bursts; use straw; allow full evaporation.
• Relubricate sliders if required after cleaning.

Precautions

• • Check plastics for solvent sensitivity; observe ESD care.
