Use neutral soap diluted with water. Take extra care
not to scratch or damage the outer surface treated
with carbon coating. Damage to this coating could
interfere with the transparency of the surface to
infrared light. Do not use ethyl alcohol, solvents,
hydrogenated hydrocarbons, strong acids or alkalis.
Using these products will irreparably damage the
germanium surface.
Once the cleaning mount the protection grid with its
screws and washers.
