The coated blades are a no-brainer - leave them alone and they are fine. The coating is very corrosion resistant by itself.
But the shiny satin blades are a different story. They are easier to stain or even rust. My recommendation is to use a little Renaissance wax as I have never had a problem when using that - but I wondered what you guys use?
