A mixture of Prepsol (wax & grease remover) mixed with old engine oil works a treat. about 40% oil 60% prepsol from memory. It sounds self defeating mixing a grease remover with oil but it does work. I would suggest trying a bit an an area not really visible to make sure it doesnt affect any markings you want preserved & it will give the finish you are after.
A dumb question but I'm going to ask it, why not use fresh new oil, won't that give you a good sheen on the hoses.
The old oil is blacker, you could probably get a similar result with fresh oil, never tried it. I was shown it when I was an apprentice many moons ago. The boss showed me on a dash pad on an old BMW, it looked like crap before & once he did that it looked like new. Then I did all the rubbers & they came up really nice. I saw the car some time later & it still looked good. I have done it a quite a few times since & never had an issue.
