CLEANING
Prepare the cleaning solution in a dilution ratio of 10% (light dirt) or
20% (heavy dirt) by volume of the approved wetwash cleaning
material to the amount of water.
Apply the cleaning solution with a low-pressure spray gun, a source of
dry compressed air or a soft-bristle brush.
Let the cleaning solution soak into the surface until the dirt becomes
soft (approximately 5 minutes).
Fully flush with a plastic hose or equivalent and clean water, three or
more times. Then, flush the surface from its top down to the bottom.

Two-step deicing/anti-icing includes deicing followed by anti-icing, as
a separate fluid application. Anti-icing fluid is applied to protect the
required surfaces. It gives the maximum possible anti-icing capability.
