This Easy Trick To Removing Rust From Mason Jar Lids
To prevent your mason jar lids and rings from rusting, keep them away from the dishwasher, wash them by hand, and make sure they are completely dry before you put them away. However, when it comes to removing rust, as Becky Rapinchuk of Clean Mama puts it, "my best tip would be to rub the rusty ring with white vinegar and wash."
You can use a clean cloth soaked with distilled white vinegar to rub and scrub away any rust or orange streak, and then use a sponge and warm, soapy water to wash the lids and rings by hand. Don't forget to completely dry them since lingering water typically causes rust to begin with.
For a heavy, stubborn layer of rust, you can soak the lids and rings in vinegar, which will dissolve the rust. However, if the rust still resists, you might want to use a stainless steel scrubber or steel wool soap to help remove any remaining spots of rust.
