I have an oil-fired water heater that collects mineral deposits from our
hard water. It's driving me nuts - bits of the stuff keep coming off and
clogging aerators, shower heads, etc. Also makes a mess when the tub is
used. However when I drain the tank almost nothing comes out - seems the
deposits are pretty well attached!

I'm wondering if it's possible to use Lime-Away or CLR to remove these
deposits, or would this damage the tank? I drained the tank, removed the
drain valve, and looked inside - it seems the layer of deposits is pretty
thin, 1/8 or maybe 1/4 of an inch.

Far better and safer to remove or eliminate the deposits before the tank.
Look into a softener and if you have solids, an in line filter. Chemicals
may remove the deposits, but you may also have residue for a while after. Do
you want to wash your hair with Lime Away? If the deposits are truly well
attached, the are not the ones you want to catch.
