Edge Connector Cleaning (Tarnished or Deeply Stained)
□
1. Use the Eberhard Faber (400A) pink pearl eraser, or equiv-
alent to remove tarnish or stains. Fiberglass or nylon burnish-
ing brushes may also be used.
NOTES:
1.
Minimize electrostatic discharge by using the 80% to 20% isopropyl alco-
hol to distilled water solution during burnishing.
2. Do not use excessive force while burnishing. Use only enough force to
shine the contact surface. Inspect the edge connector after cleaning to assure
no loss of contact surface.
