Glad I found this. I have a bunch of Lionel track to clean up. I was debating using Evaporust. Now I know what to expect. Thanks for posting.

I'll give this a try for my really difficult projects I reckon but Its fine to use sand paper, in fact the following tip comes from the Lionel's own support page "Rust can be removed with sandpaper, non-metallic kitchen scouring pads work well too, but never use steel wool on track as small particles tend to stick to the rails".

This stuff is the bomb.......I tried the vinegar and it worked........ok. My wife didn't care for the stench that comes along with it though, but the evapo-rust is amazing......little to no odor and reusable......my track turned out amazing and with no elbow grease.......definitely worth the money in my opinion.

I agree. I have been reclaiming some old standard gauge tracks. I tried vinegar which works reasonably well but Evaporust is the best! It is absolutely worth the investment.

Wow absolutely wow

I cannot tell if the paint on the ties was removed. I saw a video with vinegar on Lionel standard gauge track, and it worked well with removing rust, BUT it took off the black paint on the ties. Wondering if Evaporust would do the same on the ties.

Basically highly concentrated vinegar
