4. Repeat with a clean cloth that is soaked with the solvent
mixture.

5. Dry the edge connector contact area by wiping with a clean
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 also be used.

2. Minimize electrostatic discharge by using the 80/20 iso-
propyl alcohol/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.
