It's also important to rinse the blade afterwards and get all of that stuff out.... probably with more WD.
People use dental floss to get into the area. Although I can't imagine this helping much with rust, it helps with cleaning out various other gunk found in there.
There's another neat thing you can do, while cleaning the pivot.. I didn't quite realize this, until I was cleaning a razor with a set of transparent acrylic scales on. You load the pin area with WD, it will get trapped in there. Then take a paper towel and attach it firmly to where the tang meets the scales at the pivot. Watch that paper suck out the WD, along with the dirt, just like magic! Easy to see with transparent scales. Repeat this several times, or for as long as dirt is coming out. Leaving the pin soaked a while loosens more dirt and rust particles. Combined with dental floss, this can get it pretty clean in the end!
