Recently found several similar suggestions on youtube for cleaning rust off of small garden tools. All those suggestions start by soaking the tools overnight in white vinegar (some use a jar, others use a tray, or wrap the tools in vinegar-soaked paper towels). The next day, use some baking soda and an old toothbrush to brush the rusty areas, rinse off and thoroughly dry the tools, then cover them with a light coat of mineral oil, or some other light oil, for protection.
(Just do a youtube search for "How To Remove Rust From Garden Tools", and watch a few of those videos for yourself, to see some of the slight variations.)
You can clean off those pans and rings of stovetop burners by putting them in baggies with a tablespoon of ammonia, and letting them sit overnight (preferably outside). Next day they will scrub- or dishwasher-off very easily. We’ve made them look new that way.
