Most trains used to use cast iron brake blocks and the dust would make a mess of any paintwork. Oxalic acid was used to clean off the iron stains.

I have some milk stone remover which smells of organic (acetic?) acid. I might try this at some stage.

I like the idea of sodium bicarbonate solution (washing soda) with electrolysis. No very nasty chemicals. It did strip some paint off a storage heater when the package was left there for a few days so it now sits on a ceramic dish.
