hi,
i assume your wok is not seasoned if it is rusting -- or that the
coating is becoming weak and needs to be redone?
i'd suggest seasoning it thoroughly -- in case you're not sure, this
means doing the following (same procedure as for a cast iron pan):
1. scrub off all rust or anything that might flake off, thus
compromising you making a strong seasoning surface,
2. stick on the stove to heat dry and start your seasoning procedure
immediately:
3. get your wok smoking hot. have ready: veg oil and lots of paper
towels, and the fan on! this is going to be really really smoky.
4. impregnate a big wad of paper towel with oil (big enough of wad so
that you don't burn yourself...or hold paper towel with tongs/chop
sticks)
5. wipe a good layer of oil with the paper towel on the entire surface
of your wok in a circular fashion.
6. when the layer of oil has darkened/blackened, wipe another thin
layer of oil.
7. repeat 6 several times until you have a blackish sheen on the
surface of your wok.
you may have to do this several times to get a really good black
non-stick surface. remember, a freshly seasoned pan has a weak coating,
so treat it with care until it becomes stronger -- i.e. in the
beginning avoid cooking acidic (e.g. stuff with tomatoes) foods in it,
don't scrub it too hard (i find nylon brushes clean better than
scourpads -- they are gentle on the surfaces but still cleans well).
after awhile when the surface has had time to "season"/harden with use,
it should never rust and be a snap to wash
.. a happily seasoned wok, i think is a better nonstick surface than
teflon cos it still allows you to cook on the high heat required by
stir frying (and lends that nice smokiness to the food), and the
nonstick surface is renewable at home.
hope that is helpful,
g
btw a good way to dry your wok before storing it away is to heat dry
it: when you're done washing it, stick it back on the stove on med-high
until the water evaporates.
