Porcelain is porcelain...don't use abrasive cleaners on any of them. Don't use in-tank cleaning products (like anything with bleach in it) as they will degrade any toilet's rubber parts. Other than that, and that is true for any toilet, most anything available for cleaning the toilet should work. If you get Sanaglos, you won't have to clean the inside as much as one without it or a similar product.
