My rice cooker has aluminum, and non-stick coated aluminum surfaces.
It has built up deposits of hard, brownish material that seems to be
mostly calcium. I cook a lot of brown rice and mixed grains.

I can live with it, but my owl is more sensitive to filth. Any suggestions
for cleaning out this plaque? I've tried water+vinegar and it didn't work.
I tried scraping with a tea spoon and I did manage to damage the rice
cooker. What to try next?

overnight.

Try soaking it in straight vinegar (don't dilute it with water). It may
work better. If not, there are a number of products available for sale that
can remove calcium deposits.
http://www.wholelattelove.com/articles.cfm?articleID=29 has a list of
products for use in espresso machines (it's near the bottom of the page), so
I assume they would be safe for rice cookers, as well.

Bad choice on aluminum. Try using citric acid ("sour salt" in the ethnic
Jewish food aisle at the supermarket, or buy it at the pharmacy, or look
for a calcium scale remover that is citric acid based.

Once the stains are removed from the rice cooker, it might be wise to
use only filtered water in the rice cooker. That should prevent the
problem from happening again.

I've been using bottled water exclusively. I suppose that I could
switch to bottled "purified" water. But I suspect that the brown rice
and mixed grains that I cook leach out their own calcium.

CLR. It is available in most hardware stores. It works wonders on stains like
that. It is fairly corrosive so be careful not to get it on your skin, and
make sure that you rinse it.... a lot. It works. I have used it in coffee
makers and in my water distiller and had excellent results.
