Just a couple.

 

The intake manifold of my XJS-12 look a bit dull, how can I clean them without removing them?

Old thread but Spring is here. My preference is =

1 can of foam tire cleaner
Lift hood, no need to mask anything
Spray everything and anything, large dirt/grease deposits may require a bit of brushing with a SOFT brush or cloth
Leave for 10 minutes
Air blow off the remaining foam/suds/dirt residue (leaf blower works well if no EASY air compressor air used.)
The tire cleaner has additives that shine and protect all the plastic and rubber parts.

Looks like this (I do it monthly in warm weather) =
