My CI grate has never rusted, I soaked it in some oil before first use and then just keep it topped up with a brush of oil before cooking. The Weber CI grate I had was terrible for rusting, might just be a quality issue with them. Storage will probably have an impact, I keep mine in the Egg when not being used and wouldn't grill without it now
