i need ideas for redoing Formica counter tops

Sorry, maybe it's me but this is confusing to me. It says it is not safe to use Rust Converter on things like grills or cast iron stove and yet later on it says how it converts cast iron. Is there anything else one can use? I know to get as much rust off as possible--have done that--sanding, vinegar/water solution and put a bit of oil on it to help it from rusting between jobs. I also have areas in a small (approx. 12") cast iron stove that are hard to get to--the inside. Any other ideas/suggestions? I'm at my wits end with this project that I thought would be simple. Thank you...anyone!!
