I have a peeler that I've been using for a while. It's gotten quite rusty and dirty. Of course, I can toss it at this point and start with a new peeler... But is there any way to clean it? Anything I can soak it in that would remove the rust?
Soak in a mild borax solution. fill the sink and throw in gummed up juicers, colanders and tea-stained spoons as well.
If your kitchen is humid, a bit of an oil rub after thorough drying should slow down the rust.
