Re: Turnout point conductivity

 

Nat,

Do not worry too much about reversing loops. If you want one, it's not as big a deal as some of the discussions had made them out to be. There are few rules, and the wiring is pretty straightforward. Plenty here will help you if you need it (chances are: you won't). The really tricky discussions only arise when people start to get almost philosophical as to what happens when you have two reversing loops very close together. I think that's the discussion that looked frightening. But the normal principles? Not daunting at all.

Two cans is likely a lifetime supply for me. ?.
One thing is certain.? The subject of how to best clean track has more options and opinions than politics.
Well, except for how to properly wire reversing loops.? I am not putting any on my layout, because after all the discussion here, I have deemed it an absolutely incomprehensible subject area.

All true with regards to WT40 contact cleaner (30% heptane i.e. petrol, 20% isopropyl, rest propellant) and yet on my layout it does the job well with no issues. Maybe because moisture/humidity cannot enter the can and the alcohol actually remains in the specified concentration.

I'd be nice if the world was perfect, innit?

Tend to agree with the WD-40 contact cleaner caution.
AFTER I buy two cans, I now find it contains 10-20% isopropyl alcohol.? Groan....

But the wd40 electrical contact cleaner contains both alcohol and petroleum products , both we are told to avoid, yet its the most recommended for conductivity

What¡¯s going on with recommendations

I can highly recommend WT-40 Contact Cleaner (NOT 'normal' WT-40) which is a non-polar solvent designed for cleaning of electrical circuits and contacts. Or many other contact cleaners (I live in the UK). Leaves no residues at all. In my experience, anything that contains water (i.e. any alcohols) is unusable as water promotes oxydation (the black gunk we all hate) rather than prevents it. Any 99% alcohol after some time will contain a lot of water as the alcohol itself is so hygroscopic taking moisture out of the air when open. Other opinions are available.

I'm not arguing, but. Wiping any rail with any abrasive can lead to other problems. I quit using bright boy, sand paper and certainly never a file. My current favorite is a white wine bottle cork. And even that is rare. But to clean points, etc. I only use a liquid. As I mentioned, acetone would work, but can harm ties. So the best thing is to start with alcohol, and then the mineral spirits. That I have done and does work.? ?Morgan Bilbo, slightly over one year with very basic DCC
