So here is an example of some track. When you see a situation like this type of track.
These tracks here are pretty dirty. There’s a lot of possibilities of some rust and corrosion.
But there aren’t any divots, or dings or nicks in the track.
So this type of surface corrosion can most of the time be taken care of with a good quality wire brush.
Just give it a good brushing back and forth, just to get all of that stuff off.
