I will be willing to report to Snooze on my trials mentioned above, when completed, so several months away.

There is a big difference between graphite and charcoal! I would not use the latter on my track.
I have successfully used the carpenters' pencils, from Dad's workshop.

The procedure is to firstly select a wine which isn't in a screw-capped bottle, secondly drink the wine, sharing it with your fellow modellers, and thirdly use the cork, whole, to clean the tracks. Any dirt disappears into the natural fissures in the cork and, being fairly soft, it doesn't abrade the rail at all. In time, the cork will need replacement but by then everyone will be thirsty again!
You can use plastic corks but the natural (or compressed) ones are best.

Martin, it's not your keyboard, it is which keys and what order you press them...

My interim conclusion is that there is no advantage in using the expensive and inconvenient aerosol WD40 Contact Cleaner.
Comparison between Propanol aka IPA and Heptane is ongoing. The results are pretty much the same in my operational trials and so far there is nothing to choose between them in performance for track cleaning.bgb
My reading of the COSHH data is that toxicity is similar.

Propanol is not IPA. Propanol is propan-1-ol whereas IPA is propan-2-ol

True, my mistake. All my remarks refer to IPA, I should not have mentioned propanol.
Commercial Heptane, which I am trialling is usually sold as a mixture of the many isomers that exist. I have no idea which of the 9 isomers is most effective for our application. Even if I knew, I suspect that trying to buy a lab. grade of any one isomer would be prohibitively expensive.
In the case of IPA I wonder if some vendors' versions also include the other isomer ?
