Cleaning Track

I searched "cleaning track" and for the most part it ignores the "track" term. I scanned a few pages of the search and nothing popped out as far as track cleaning. So I apologize if I didn't search far enough, but would some of you direct me to a 101 track cleaning technique of my Carrera 132/124 track for non-serious home racing? Or maybe suggest products and techniques.
I typically wipe the track down regularly with a lent free cloth. I use 70% Alcohol to clean tires now, but after watching video when I renewed the hobby 2-1/2 years ago, I did (and occasionally still do) clean tires with WD40. So I do possibly have some solvent residue along with whatever gear grease and bearing oil that might have been emitted by the cars in the past 2.5 years.
Thanks!
