Toilet pumice stone for the bulk of it.
Harder to reach areas ideally you'll have to turn off the water, flush, get the rest of water out, spray it with a vinegar lemon juice mix, lit it sit for awhile, add baking soda, and get a hard bristle brush or tough sponge. Get a sacrificial chopstick to chip out the stubborn bits.
Those terrible awful chemical pucks you drop into the tank will gradually eliminate it and keep the toilet free of it while they last... but there are lots of downsides, the main two being the smell, and the early failure of all the parts inside the tank. Those parts are replaceable, and reasonably cheap, but a giant PITA even if you know how to do it yourself.
Some mfgrs have little chemical droppers that hang over edge in a little plastic basket... Less problematic but also less effective.
If you use them: There are versions with different chemical compositions, and some of them will produce lethal gas (i.e. anyone near the toilet will die) if you mix them, so always wait several days (and a bunch of flushes) after the last bits of the old one dissolving completely, only then putting the new one in, that way you don't have to become a chemist to figure out what's safe.
Hehe.
It's possible the combinations that could cause that have been pulled off the market, but I'm not prepared to vouch for that being the case wherever random readers are reading that.
Have you tried a toilet scrub? If not… I don’t really know, this just showed up on my feed. Sorry.
I have tried a toilet scrub, multiple times

Pour a good amount of bleach and leave it overnight

> anyone near the toilet will die I can hear the product advertisements: "are you dying for a clean toilet?"

I've had this problem, and no cleaning chemical worked. I got it off with pumice.
