Hey Leon, have you tried The Works toilet bowl cleaner? This is not great advice because it is extremely toxic and I hate to use it as I go all natural in my home. However, with my incredibly hard water, I've had to break down and use it a couple of times to get off calcium deposits in my tub and toilets. I haven't found anything that it can't clean up yet! But be very careful with it!
Easy Off should work. It gets off Tough Burned on Grease.
CLR (calcium, lime, and rust) works great with a stiff brush
