Oiling a trigger? Really?
Yes really, since you claim rust is the problem.
Or did you forget that?
The metallurgy in the trigger group is suspect and when introduced to Kodiak-style rain it oxidizes so fast the linkage wire freezes the trigger to a locked-up and useless mode.
Generally it takes about three days of "Tuesday" to cause it. Few make it past a week. If they do they will likely never be a problem.
You never put oil in a trigger. That is the dumbest idea one can do. Why no grease up the FP Assy while you're at it.
Like I said, lighter fluid has a metal anti-corrosion property to it. Saves your favorite Zippo from corroding. This works well for triggers to clean by flushing, then dries quickly and completely, leaving a protective film that wont keep and hold every spec of dust, dirt, and grime that it comes in contact with.
Oil goes nowhere near a trigger...
