I have a soft baby coverlet from my oldest that I have been using for almost 30 years which is partially impregnated with RIG. I keep it in a quart ZIP lock to keep it clean.
My preparation of it was that I used it for about 3-4 year to wipe down excess grease after application of the RIG to the surface of my firearms.
Since then, it has maintained just the right amount of grease to clean away finger prints and adequately apply a thin coat to the gun for me.
So far, RIG has kept my blued guns rust free. Didn't see a purpose to experiment further.
