I heard about a product called No-Ox over one year ago and my club decided to give it a try. The results are amazing. We have only cleaned the tracks on our extensive layout 3 times in one year. We gave the tracks a complete cleaning job and applied a very thin layer of No-Ox over all the rails. We did not clean the tracks again for 4 months even though we run many trains every weekend. The tracks have a film on them but our members have all been told..Do not clean the tracks. Once in a while you can clean your locomotive wheels but leave the tracks alone. Our trains run around with not a flicker from the engine lights. No-Ox stands for No Oxidization.
