JohnsonDiversey "Titan Sanitiser" works a treat for getting rid of FeCl 
stains. Rinse the sink out to dampen it, turn off the tap and count to 
ten. Cover the inside of the sink in the stuff (it's a powder) and rub 
it on the stains. Rinse away the remaining powder (it's water soluble).

Make sure you wear gloves! This stuff is nasty -- it's used for 
disinfecting hospital floors. If you can't get hold of it, Swarfega 
might also work. Essentially what you want is a substance which is both 
a mild abrasive and a detergent.

As long as you don't, say, wait a day between using FeCl in the sink and 
cleaning it, you should be fine.
