I wound up getting an older Traynor for someone that had been sitting in a practice space (a dirty one) for quite a while and was pretty grungy. I've heard of people using Armorall on Tolex, but I really don't like dressing type stuff for any vinyl or plastics or anything like that. I detailed cars on the side for a few years and got really into high end detailing products, and found my favorite thing for cleaning dashes and interior plastics was this stuff called Einszett 1Z Cockpit Premium. It's just a cleaner, not a dressing so it doesn't get greasy or anything, just clean and matte. I figured if it will clean dashes and lcd screens I'd try it on the Traynor, and I was really impressed. Cleaned it up perfectly, left the Tolex exactly how it should be. I love good products that multitask!
