Well, not exactly lies maybe, but questionable statements anyway. Please read the following and tell me what you think. They were statements made to be by my LHS. They are not all from one individual, BTW.
1. Track cleaning cars are not efficacious. They do not really work all that well. None are worth the price. The best method of track cleaning is by hand with track cleaner applied to a soft cloth.
2. No need to fasten Fastrack to your layout. If it is part of a larger system of any size it will not go anywhere or come apart. Nailing it, or screwing it down only makes it louder.
3. All brands of smoke fluid are completely interchangeable. It doesn't matter which manufacturer's smoke fluid goes in which manufacturer's engine. This one I kind of believe. (Naturally sellers of engines want you to buy THEIR accessories)
Thank you for any responses you may have.
I am especially interested in your answers to #1 as it is very inconvenient and a stretch for me to reach some parts of my layout to clean track by hand. I'd love to get a track cleaning car that actually works. But I am inclined to believe my LHS on this point.
