Which of the following are acceptable to use when utilizing chemical cleaning agents on aircraft?

• A. Atomizing spray equipment
• B. Synthetic fiber wiping cloths when using flammable agents
• C. 2 and 3
• D. Cotton fiber wiping cloths when using flammable agents

Answer: (C)

When using chemical cleaning agents on aircraft, you must choose wiping cloths that won’t shed lint and are compatible with the solvent. Both synthetic fiber wiping cloths and cotton fiber wiping cloths can be used for this purpose, provided they are lint-free and suitable for the specific chemical. They offer effective cleaning without leaving fibers behind that could contaminate surfaces or systems. Atomizing spray equipment, on the other hand, creates a fine mist and vapor that can raise ignition risks with flammable agents, so it isn’t considered acceptable in this scenario.
