C. Remove insulation blankets and components (power drive units, actuators, exposed electronic equipment, etc.) which may be damaged by cleaner or water.
CAUTION: FABRIC, MECHANICAL AND ELECTRICAL/ELECTRONIC COMPONENTS MUST BE REMOVED TO PRECLUDE DAMAGE.
D. Mask all areas not to be cleaned, including all lubricated or waxed surfaces and any cargo door latch mechanisms and fittings. Use polyethylene sheet, greaseproof paper or laminated waterproof paper as appropriate. Secure with masking tape as required.
CAUTION: CONCENTRATED CLEANERS MAY CAUSE PAINT TO DETERIORATE OR MAY CAUSE CORROSION OF METAL SURFACES IF ENTRAPPED. MANUFACTURER'S RECOMMENDED DILUTIONS MUST BE-USED TO PRECLUDE DAMAGE.
4. Clean Cargo Compartment
A. Vacuum bilge area to remove loose surface soil.
B. Pressure spray Alkaline Solvent Emulsion cleaner using airless pump with spray valve and non-atomizing nozzle.
WARNING: CLEANERS CONTAIN TOXIC INGREDIENTS. WEAR PROTECTIVE GLOVES WHEN USING THEM, AND AVOID CONTACT WITH SKIN OR EYES. PROVIDE ADEQUATE VENTILATION OR USE RESPIRATOR MASKS. CONSULT INDUSTRIAL HYGIENE, FIRE, AND/OR SAFETY ORGANIZATIONS CONCERNING FACILITIES, EQUIPMENT, VENTILATION, AND OTHER REQUIREMENTS FOR SAFE CLEANING OPERATIONS.

(3)
If pH exceeds 1 pH unit of incoming rinse water, repeat steps F. and G. until pH is within 1 unit of incoming rise water.
I. Wipe area dry.
J. Apply corrosion inhibiting compound on cleaned area (Ref 51-21-91, CP).
