I noticed a bit of rust around mine as well recently. I removed the plugs for each jack hole, dried out the hole and added some spray grease, then re-installed the plugs. I think moisture gets trapped in there, behing the plugs, and causes the rust. I'm hoping the grease will do the trick. Not a bad idea to remove them a few times a year and dry out the holes, either.
