Subtask 12-21-11-615-071-A

A. General Instructions before Cleaning
(1) General cleaning procedure
Do the steps in this cleaning procedure for each zone:

Spray the zone with water.

NOTE: This decreases the surface temperature of the aircraft and prevents drying of the cleaning agent on the area before you rinse. Also, it is easier to rub a wet surface than a dry surface.

Apply the cleaning solution with a sponge or spraying equipment and rub at the same time.
Let the cleaning solution soak but do not let it dry.
Rinse the zones with water in the sequence in which you applied the cleaning solution.

Do not let the cleaning solution dry on the surface of the aircraft before you rinse it.

NOTE: If the weather is very hot, it is necessary to clean small areas. This is to make sure that the cleaning solution does not become dry on the external skin.

On painted surfaces, rub the surface with a SPONGE or a BRUSH - BRISTLED, SOFT.
To make the removal of the remaining dirt easier, soak the BRUSH - BRISTLED, SOFT or the SPONGE with the cleaning solution before you use it.
Carefully rub the surface with moderate pressure. Clean the brush/sponge frequently to prevent scratches.
(2) Areas where special precautions are necessary
(a) Windows
Refer to the procedure given in the paragraph: "Cleaning of the Windows".
