My utility toilet I had planned on replacing because of the state of it from limescale but I absolutely went to town on it over the weekend and it looks good as new.
It was pretty much as bad as it gets, any part under the water line was totally dark brown and round the rim it was shocking too.
Filled the toilet up with just a cheap Aldi toilet cleaner and left it a few hours, then put toilet cleaner soaked pieces of kitchen towel around the rim and left that too.
Got most of it off with a good scrubbing after that, but had to use a wallpaper scraper on the bits around the rims
