gasoline > degreaser (to get rid of the oily film residue) > methylated spirits/denatured alcohol.
Works perfectly everytime.
I tried mineral turps/white spirits prior to using gasoline and I found that mineral turps/white spirits did not remove entirely the grease inside or even on the outside of the chain. Gasoline removed it all.
For those not keen on using gasoline, what are your suggestions for an alternative that does just as good a job?
