To clean the PWD Forward Scatter Sensor lenses, no parts have to be
removed.
1. Wipe the lenses with a soft, lint-free cloth and normal glass cleaner
or isopropyl alcohol. Be careful not to scratch the lens surfaces.
The lenses should dry up rapidly. There should be no wiping stripes
or remaining dirt on the surfaces. See Figure 113 below.

2. Check that the inner window surfaces are free of any water
condensation.
3. Check that the weather protection hood is free of ice or snow
deposits.
4. Wipe the dust from the inner and outer surfaces of the hoods.
NOTE
Do not use any sharp tools to remove ice or snow from the hoods,
especially from their heated surfaces. This can easily break the heating
foils. Do not try to insert any tools under the foils because the foil glue
may then fail to hold the foil on the hood surface. It is essential that the
foils are firmly attached to the hood surface, otherwise the heat transfer
from the foil piece to the hood is impaired resulting in a burned foil.
5. After the windows have dried up, the cleaning activity should be
finalized with the CLEAN command (A) for the PWD Forward
Scatter Sensor. Select PWD Sensor (G) from the maintenance
section on the Main menu page (see section CLEAN Command on
page 241) to
access the CLEAN command.
