Due to some emails regarding the intermittent operation of various products on folks layouts I started asking questions regarding what they used to clean their track. Much to my surprise 90% of those questioned said they used rubbing alcohol, or isopropyl alcohol.
I did some research and discovered the following information that may be a surprise to those of you out there who are currently using rubbing alcohol to clean your rails and wheels.
The chemical formula for isopropyl alcohol is (CH3)CHOH. While, to many of this it looks like something we tried to forget soon after graduation, the last two letters of the formula are what I am concerned with. "OH". OH is Hydroxide. Hydroxide is a corrosive, much like lye or sodium. Corrosive means it promotes rust. When using a solution that ends in OH you are not only dissolving carbon dirt, but you are introducing a chemical that does not promote good electrical conductivity and does promote corrosion (rust). It is essentially the same as cleaning the rails with water.
This corrosive effect works the same on steel rails as it does on aluminum rails. I would imagine has similar effects on nickel silver and stainless steel rails too. The end result may be a clean set of rails, but what also comes with it is degraded electrical conductivity. So, how do we fix that?
Many of you may cringe at this point! But WD-40 is how you reverse this effect. WD stands for "Water Displacement". It effectively removes the OH deposited on the rails and leaves them clean (and also substantially promotes electrical conductivity!). Now, it is important to note that you need to wipe the rails completely with the WD-40 as well as completely wipe off as much as possible, as it will effective the traction of your locos with traction tires. It will eventually wear off over time (an hour or two of running) but the electrical conductivity will be unlike anything you have ever experienced on your pike!
So, what do you use to clean your rails if isopropyl alcohol is bad? Here at Lionel service we use Goo-Gone. (http://www.googone.com . This is a citric based cleaner (just to be sure I researched its chemical composition and it is CH3OCH2CHOHCH3 the breakout is; 1-Methoxy-2-hydroxypropane, 1-Methoxy-2-propanol, 2-Methoxy-1-methylethanol, Propylene glycol methyl ether. The product does not end in "OH" which means there is no hydroxide or corrosive chemical in this material. The Goo Gone dissolves the dirt and allows you to clean the rails without having any negative impacts left behind.
I extend this challenge to you; if you have areas on your railroad where locomotives hesitate, lights (on locos or cars) flicker, sounds drop out, basically any undesirable operation take a little WD-40 on a rag and wipe down the rails in that area, apply the material, then wipe it off. You will be amazed at the improved performance of your trains in that area. (now, do not confuse what I am saying with command signal interference issues, different topic, different solution). I am referring to the electrical pickup to the trains from the track!
For those of you who have lighted passenger cars and have flickering lamps inside when the train runs around the layout, wipe the collector rollers with a Q-Tip (with a little WD-40 on the end) and then wipe it off. Then using the spray straw put a small squirt in the bearings where the axle ends insert into. Just a tiny squirt is all that is necessary. No more flickering lights!
Hope my research is able to help you enjoy your trains more!
Thank you,
