Being a cleaner, you can mistake some common cleaning agents as useful for cleaning aircraft interiors; however, they can have repercussions. That is why avoid window cleaners that have ammonia, product cleaners specifically for wood, regular dish soap, MEK (Methyl Ethyl Ketone), and Chlorine based bleach. Usually, you’ll be trained on which chemicals are safe to use and how to apply them, but if unsure, ask your tenured colleagues or supervisor.
