    You should drain the tank and clean with Coca Cola and/or degreaser. You can find degreasers by the paint area at Walmart or at your local hardware store.

    Lysol toilet cleaner in the blue bottle works best for me. I actually scraped a toilet with a paring knife when the black was so thick I could chip or scratch it off. Nasty job. Good luck!
