I use CG APC diluted 10:1 minimum, 15:1, or even 20:1, with great results.
Lately, I'm relying mainly on Meguiar's #39 do clean trim and rubber, it's very effective and fast.
After cleaning, I generally apply either 303 Aerospace protectant (to internal / interior parts), and coating to external parts.
Some examples:
Before (gas compartment)
After (cleaned / renewed with #39 and protected with 303 aerospace)
Window trim, before
After Meguiar's #39
Same car, more trim cleansed and coated:

Another car (yet silver), more trim, before:
During Megs #39
After
Rubber seals, before
Used All Clean Plus Citrus APC 15:1 with a soft brush (won't either scratch your teeth!,

)
After coating, (even looking nowadays seems to have lasted little wax from other guy, but compared to before the difference is 99%).
There are many more.
I also have used some of Mother's Back-to-Black cleaner on porous trim, where I would generally scrub either using the brush provided, or a MF towel with some 'nap'.
Hope that helps,
Kind Regards.
