For tiny rust spots that just won’t quit, make a paste. Mix baking soda with a little water until it’s the consistency of toothpaste.
Slather it on the rusty spots and let it sit for 30 minutes. Then scrub with a damp cloth or sponge. The baking soda acts like a gentle exfoliator—it’s basically a facial for your grill.
Rinse off the paste, and you’ll see the rust dissolve like your willpower at a dessert buffet.
