Should I clean the rails with a particular solution? Can the Verdigris travel eventually from the rails? Do we know facts about what will happen in 50 years on the verdigris problem? Thanks! Lance Lafargue, RPT >> I clean the rails with Brasso. It is my understanding that the green gunk comes from a reaction between the center pin and the felt. What is on the rail is just an "overflow" of that stuff. In other words, it wasn't "created there". So if you clean it, it will not come back, or reproduce on its own. Willem Blees RPT St. Louis
