Japanese black cast iron tetsubin kettle turned grey from overheating
Posted: Thu Jan 12, 2023 4:13 am
Hello,
I have a problem with my Japanese black cast iron teapot kettle, recently I forgot it more than 1 hour on the fire of the gas stove.
it has oxidized and become rusty underneath.
I read on a web site specialized on japanese waxes that you have to soak it in a mixture of 50% water and 50% vinegar, which I did, then I scrubbed it with a plastic stiff bristle brush. the problem is that, even if the rust is partially gone (if I keep scrubbing I think the rust will be completely gone), the treated areas now appear grey.
Is there any solution to make the surface look like it did initially, i.e. black and more uniform ?
This is a gift to my japanese wife, she is coming back in one week, And I would like to fix it before she's coming back
Thanks
