Try the plastic spiles and you will likely not go back to the steel ones. For one thing, those steel ones want a 7/16 hole, most plastic ones use a 5/16 hole in the tree, which closes up faster after pulling them. On plastic however you want them new each year, unless you use the zap bac ones, they are used 2-3 years.
One other way, using the steel spiles, clean them, then pack them in an oil such as canola, or safflower or similar. Then clean them in the dishwasher before tapping next season. That should prevent the rust.

Dave Klish, I recently ordered a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.
