A few years ago, I wrote a bit in GR about how I think any form of abrasive cleaning is asking for trouble. Once the brass rail is minutely scratched, you are providing a repository for dirt to collect.

I've never cleaned my track outdoors in the 7 years it has been down. I use track power, and put a few drops of fine oil similar to Whall on the rail for the train to spread. When the trains get sluggish, on goes some more oil. Works for me.
