ActiveClient. You are right about 3M maintenance, but you are also wrong. I am a contractor now but when I was in the Navy I would take that card around to clean up the fire nozzles. We used bug juice (koolaid) to soak the brass, cleaned really good along with a wire brush. Not any where on that card does it state to use bug juice. I got out in 94' so maybe things have changed.
Happy Veterans Day by the way to all service members, active, retired, and discharged.
