Just leave a denture tablet in your toilet overnight and flush in the morning -- that’s all you need to do to get tough stains out of your toilet. For more follow the hashtag #RachaelRayShow
This doesn't 100 percent work. I have a newer home with a septic system and use county water supply. My toilet started having stains because of recent septic tank issues- the toilet was not flushing all the way, tank was filling slower, etc. Regular toilet bowl cleaner was not getting all the brown stains out of the toilet. I saw on Hunker how you could use 6 denture tablets dropped into your toilet overnight and scrub your toilet the next morning using a toilet brush. This trick only partially removed the brown stains that are directly in the bottom of the toilet. I'm going to have to try Borax or Lime Away to see if it works better.
