The following isopropyl alcohol method is provided for the cleaning of the soft goods and aluminum parts of
system components. The method for non-ionic detergent is the same procedure as that in paragraph 4-65.
CAUTION

Personnel should wear chemical protective gloves to prevent skin irritation
when contact with isopropyl alcohol is necessary.
