Super-O track rust issues

I would give up on the Scotch Brite, alcohol, and Evapo Rust. All three will promote rust. Clean the track with a petroleum solvent like mineral spirits and wipe clean with a dry clean rag.   Install a humidity gauge to your train room and if the relative humidity gets above 40%, start using a dehumidifier.  That should stop the rusting.

I've heard of people sandblasting track to remove the rust, but never have seen the results or reports on how well it stood up five years later. 

You might try mineral sprites (alcohol is water based) for track cleaning and then apply NO OX  ID A spec track cleaning treatment.  NO OX is a paraffin based, conducting grease and should prevent rusting of the the top of the tracks.  It is wiped off and does not affect wheel traction or traction tires.  It also will eliminate track cleaning for life! I have not had to clean my tracks in over 2 years since applying NO OX and train operation is much improved especially at low speeds.

You also could apply it to the sides of the rails and that should help rust there.  I do not mind rust on track sides as it more like real train rails.

All you want to know and more on NO OX is in the OGR forum topic linked below.

Try wd-40, let dry 24 hours, then wipe of excess.
