Cleaning with isopropyl alcohol

IPA isn't the best cleaning solution for track & wheels, something like CRC Contact Cleaner & Protectant will last a lot longer.

I use 91% isopropyl alcohol for cleaning Atlas O solid nickel-silver rails. I prefer it because it is effective at removing dirt from the rails and doesn't leave any residue.

True, but the cleaning doesn't last nearly as long as using some other products.

See this post on the dielectric constant of various cleaning fluids and their effects.

Here's the whole article on track cleaning describing that table.

Very true.

IMHO, considering it's a small Christmas layout, I don't think longevity should even be considered.  Go with what gets it clean.
