The aluminium finish on my engine components is rather faded and looking pretty sorry for its self. What would be the best means of improving this ?
If you prefer the aluminium finish you can you some high temperature aluminium paint.

Some tips from other topics :
Have ordered the autoglym engine cleaner and vinyl and rubber care today. Will let you know how and if it worked
Chemicals! Wonderful things are they not? 
That actually looks AMAZING!!!
Technique???
So all pipes and hoses I used auto Glym rubber and vinyl. Spray a bit onto microfibre cloth and wipe on / off as per instructions on bottle also for the rubber seals on the edges
Engine block I used WD40. I started using a wire brush in discrete area but didn’t like that it made fine scratches so used just a stiff plastic brush and then wiped off with microfibre - before and after in link a few comments above
For the plastic bits like filter cover, top of headlights I just used black trim polish (trim restorer / back to black )
For the painted bodywork, just sponge and bilt hamper shampoo to clean but didn’t want to drip everywhere so was careful. Then used a bit of bilt hamber autobalm
Great result
