When steel is run through the roller mill to progressively bring it to it's sheet thickness it effectively ends "forged" with very high compression and, to a certain degree, refined inpenetrability as the final surface. This is generally pretty resilient to surface corrosion as it's just so compacted, with any subsequent disturbance causing reduction of that finish whether starting with corrosion which once removed have partly destroyed that finish. All subsequent treatments by removing rust can't reinstate that first finish status, at which point it will need some element of protection. What that is I'm not sure in terms of effectiveness, but it can't be just left alone.

I assumed they had a coating of some sort like yellow zinc!
K2-K6:
I'm not aware that they were coated in any way. By comparison some of the inside of fuel caps are zinc plate with a clear and obvious difference to the tank internal.

I'd better hurry up and de-rust my spare tank then.....at this rate diesel will be nearly extinct!
Oz350Four:
I've used 2 stroke fuel mix as I didn't have diesel at the time and it worked a treat...

As Julie says, rinse with D,I water then rinse with diesel, as a former metal chemist i could go deeper but won't.
