Have some rusty tools that could use a good cleaning? When your workshop or gardening tools have oxidized and turned rusty, you can easily wipe away the rust by using a kitchen staple: a potato. Potatoes are high in ferric oxalate, which turns the rust into a sludge-like substance that is easily wiped away. Cut a potato in half (perhaps use spuds past their prime) and wipe away. Or grate a potato, cover the whole rusty tool and let it sit for a few minutes. You'll see the rust soften and be ready for a quick cleanup.
