🔍 Key Concepts

• Electrical contact maintenance – what you want to remove (grease) vs what you must protect (the metal and contact surfaces) • Effects of abrasives and solvents – how wire brushes and strong chemicals can damage or affect electrical equipment • Safe cleaning methods – methods that remove contamination without leaving residue or causing damage

💭 Think About

• Which method removes grease without scratching, pitting, or deforming the contact surface? • Which option is least likely to leave behind conductive, corrosive, or insulating residue on the contact? • Which choice would be considered safe and practical for routine maintenance on electrical contacts on board?

✅ Before You Answer

• Eliminate any option that can physically damage the contact surface (excessive abrasion or impact). • Eliminate methods that could leave harmful residue or introduce additional contaminants or moisture. • Pick the method that is gentle, residue‑free, and appropriate for delicate electrical parts.
