lint-free cloth.
To clean tarnished or deeply stained edge connector contacts:
1. Use an Eberhard Faber (400A) pink pearl eraser, or equiva-
lent to remove tarnish or stains. Fiberglass or nylon burnish-
ing brushes may be used also.
2. Minimize ESD by using the 80/20 isopropyl alcohol and
water solution during burnishing.
3. 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.
4. Wipe clean with a lint-free cloth.
