You can polish the surface with a fine grit wet/dry sandpaper. Don't use anything lower than a 400 grit. This works great, it will grind away mineral deposits and smooth the porcelain, no harsh chemicals needed.
Or, if you prefer:
Try rubbing the marks with some baking soda and a wet towel or sponge.
And as a last resort:Pour a cup or so of bleach in the bowl and let it set all night.
Turn off the water to the toilet and flush so that no water is in the bowl. Add CLR (available at most stores) and let it sit for the rec commended time. Brush to clean. Turn the water back on and flush.
That's not a stain, it's a scorch and probably impossible to remove.
Buy a new carpet! Unfortunately that's the only answer

Skidmarks account for 84.7% of all brown marks in a toilet bowl . Followed in a distant second place by Iron in your water.
short answer is you don't. My experience with the Bru stain is to persevere with a good upholstery cleaner that you trust. however I dont think it really disappears...........
Iron marks burn the fabric, which damages it, so it may not be removeable. If you can get the black mark off, the fabric underneath it will be weaker than it originally was. To try and remove the stain, scrape off any charring, then pretreat the stain, rinse it, and then wash it as you normally would.
The best way to remove oil stains from leather is to use a smoothing iron and blotting paper.
Many things can cause iron stains on the vinyl siding of a home. The best way to remove these stains is to use tub and tile cleaner and a cloth scouring pad.
You should first make sure that it is actually a stain an not a burn. Then I would recommend using bleach. If bleach doesn't work then you might try Oxy-clean.
First you want to freeze the wax so it becomes brittle and is easy to remove. Bend the wax and remove most of it from the cloth as it breaks. Place a paper lunch bag over the wax and iron it with a hot iron. Whatever wax is left on the table cloth will transfer to the bag.
