Treating Interior Frame Rust?
I know that ths is a topic that has come up before, but I did a superficial search on the forum for articles and haven't found what I was looking for yet. I have a steel frame that shows rust down the seat tube and I'm sure it's in other areas. I was hoping to build up this bike over the weekend, but it's such a nice frame I wanted to clean and protect the interior first. What recommendations do you have for cleaning and preserving a steel frame that won't damage the exterior paint?
