🔍 Key Concepts

• Purpose of silver plating on electrical contacts and why you want to preserve it • Difference between burnishing, filing, sanding, and knurling in terms of material removal and surface finish • Manufacturer and USCG/ABYC best practices for cleaning electrical contacts

💭 Think About

• Think about which method will clean and smooth the contact surface without removing too much silver plating • Consider which tools are meant for precision cleaning of contacts versus reshaping or cutting metal • Ask yourself which method would leave the contact surface smooth and conductive, not rough or grooved

✅ Before You Answer

• Verify which method is specifically designed for electrical contact maintenance • Eliminate any option that would significantly remove plating or gouge the metal • Choose the method that produces a smooth, polished surface instead of scratches or grooves
