I just realized I'm about to use some of this on a module and I haven't cleaned it yet.Will my regular bright-boy clean it up enough, or do I need to get out some mineral spirits?
Bright boy tends to scratch, and may leave other residues. Suitable for 50+ y.o. brass rail, I suppose.For the rail heads, start with #800 automotive sandpaper wrapped around a small wood block and work your way up to #2000. That should keep the scratching to a minimum, tho if you have a lot of track it will take a lot of time (not to mention sandpaper). For a spot to solder feeder wire, and/or for the ends of the rail where a joiner will go, you can use a small wire wheel in a dremel. Be sure to get the blackening off the bottom of the rail.(Then, after using up the usual stable of four-letter words (and inventing a few new ones -- a true art, much like Ralphie's father), I decided never to buy weathered rail again.)Ed N.
I definitely use the wire wheel on the bottoms when soldering. I do the same thing on the ends where rail joiners go too.Not gonna lie, I'm absolutely tempted to do it to the rail heads too... I won't, but I'm tempted.
And yeah, I ended up using the weathered track on this project specifically because I made the mistake of buying a pack of it 20 years ago and am trying to use it up.
The track is chemically blackened (not painted or stained). Abrasive or mechanical cleaning (like bright boy or similar) is the only way to remove the blackening. Solvents will not affect it. But since abrasive cleaning will likely leave small particles of the blackening, metal, and/or the abrasive itself behind, it makes sense to clean the track using your favorite non-oily cleaning liquid. If you like to protect the clean metal with some sort of oily film then after cleaning you can the coat it with your favorite rail protectant.
Unless someone performs some scientific testing and presents concrete test results stating that"scratched" railhead due to using abrasive rubber cleaners (like Brite Boy or similar) makes degrades the electrical pickup quality more than the cleaning methods using finer abrasives or even the "gleam" method), I will use whatever method is easier for me.This is one of those subjects where we have multiple views on the same subjects but without any concrete of one method being better than the other. I don't care if I see electron microscope images of the scratches. I want to see measurable proof that those scratches negatively affect electrical pickup. Show me the proof!This is sort of a thing like some members of the Mazda Miata Owner's club using Baby Shampoo to wash their cars, because the cleaners specifically designed for washing cars are too harsh on the paint.
Show me the proof!
