Currently for the interior i've been using Autoglym interior shampoo, its good on anything like your plastics and fabrics.
And it smells like lemons
By the way, I dont think i saw any post above regarding products for the exterior bumper trim pieces and rubber seals for the windows, since the black plastics fade out over time, and the seals dry out and lose color. For those parts i use Autoglym bumper and trim gel....looks like alien jizz but works like a charm
