Well I finally received my latest eBay bargain, with the package containing 11 straight and 39 curved pieces, as well as every bit of electrical hardware you need to get those babies running and a couple of switches (yeah, of course I'm bragging, you have no idea how long I'd waited for this moment! :P ). That's all neat, but I'm still waiting for my BNSF train to arrive, along with my first (and only) 9V engine sometime next month. In the meantime, I thought I'd take out the tracks and have a good look at them and boy, was I in for a surprise... Since those babies are second hand, some of them are in a downright dirrrrty condition - the switches especially seem to have been fully garnished with dust & stuff. Seeing as I really don't have any experience with those pieces and they're electric, I don't want to spoil anything while cleaning them or render them useless in some way. So before I get started, I'd be extremely grateful if you guys could give me any basic guidelines regarding the cleaning of 9V tracks - what to do and what not to. I guess a damp cloth, some kind of cleaning solution for the really dirty spots and a lot of drying out after the cleaning process would suffice, but I'd still rather ask before ruining 50+ pieces :) Thanks in advance!
