Corrosion and rust visible on generator frame and electrical connections

Safety first: Turn OFF the generator, disconnect battery negative, and ensure no live AC is present at exposed terminals before cleaning.

• Clean corrosion: Use a wire brush and contact cleaner on corroded terminals and ground points. Replace severely corroded lugs.
• Apply protectant: After cleaning, apply dielectric grease to electrical connections and a rust‑inhibiting spray to metal surfaces.
• Improve drainage: Ensure the generator pad is above grade and that water does not pool around the base.
• Seal enclosure: Replace worn door gaskets and ensure all access panels close tightly.
