Hi Doug, Since my layout is a 24" x 80" Hollow Core Door, a couple of minutes with my Cratex cleaning block and I'm good to go. The one thing I'd really like someone to confirm, if you apply NO-OX-ID A-SPECIAL to your track after cleaning, is it really "years" between track cleaning sessions or is this an overstated claim? I understand your issue with certain products used to clean track and their negative effect on traction tires. On a side note have you ever tried Bullfrog Snot instead of replacing the traction tires? Since I've been in the hobby I think I've tried all the latest fads, Wahl hair clipper oil, transmission fluid, Rail Zip and none of them were the answer for me. Sadly all of them over time just left my wheels and track a oily mess. I'd also like to mention that my layout is currently in our spare bedroom. I'd prefer not to use any harsh chemicals or solvents in our living space like some of the items mentioned in the above list. So for me for the foreseeable future, I'll be cleaning my track with my Cratex cleaning block and cleaning my locomotive wheels using the Isopropyl Alcohol tissue method. And before anyone tries to tell me Isopropyl Alcohol is a harsh chemical, what do you think they swab you with just before you get your flu shot or any other vaccination? Something to consider, I worked for a few years in the petroleum industry and petroleum products are known to cause skin cancer. This is something to consider while choosing a track cleaning product. The Cratex Cleaning Block and Isopropyl Alcohol method has been working for me, but I'd still like to know if the claims about NO-OX-ID A-SPECIAL are true?
