I've watched all the discussions on restoring the color to oxidized hard rubber pens. The easy solutions seem to be centered around restoring some sort of oil or ketone content to the surface of the pen. I've seen suggestions on using things like olive oil or parrafin lamp oil.
My question is this - does regular use of a hard rubber pen help keep the color fresh? It seems that most pens we discuss have been sitting in a drawer and not being used for years. Would the oils of our hands actually help delay the oxidation process?
