We bought the San Souci less than a month ago.  It arrived last week and was installed today, however upon inspection found the hole inside the toilet where water sits was filled with what appears to be rust.  A lot of rust.  About to try for the tenth time to clean it with some CLR (Calcium, Lime, Rust) stuff but y’all may be getting a call really soon cause this is just silly and unsightly.  But long as one doesn’t open the lid, it looks nice at least?
