Knives cai dao

F3rgus0n (Q&A ID 2781)

After I read the cai dao article I bought a knife and it is the best knife for chopping herbs and vegetables. And it rusts.

I wash it with a silicon sponge to remove the rust and oil it with mineral oil. It appears clean but when I chop an onion I have faint rust on the onion. The cai dao will have a rusty smear.

Can someone address the use of the cai dao and the use of “rusty onions”!

The simple solution is Camelia oil! Used by Japanese cooks to keep their carbon blades rust free, wipe it on. and wipe dry with a paper towel.

For rust spots, use a little coarse salt and neutral oil to scrub the blade clean.
