I personally do pretty much the same clean it thoroughly, wipe it down with a thin oil , and then wipe off all the excess I can . I use Red+Tacky grease on spring ends . And on the spring itself I just use the tiniest amount of oil just enough to keep it from rusting and then wipe it dry also . The only reason I use any grease at all is that I had two different rifles that the spring tried to bind just the tiniest bit in rear over the spring guide .
Total lube I use on a rebuild is less than 1 drop of oil in size
