We are getting 2 rust stains that run down the inside of my porcelain toilet. What cleaner can I use that won't damage the seals or holding tanks to get that rust removed? And if any one uses water filters to keep the rust and water odor out, which ones are the best? We camped at a place where the WATER was AWFUL, Well water. We would like to protect our Monty from this happening again.

Thanks,
Sharon
