Door Panel Cleaning?

[Floyd]

Any recommendations for cleaning/restoring interior door panels, seat backs, etc?  Is there any way to bring back a uniform luster through a cleansing technique or some type of chemical treatment.  Not looking for the Armorall solution, although I've used Vinylex with some limited improvement in the past.  I'm guessing there's no magic bullet, or Metro wouldn't be in business..  Does pressure washing work at all?
Thanks

If you can't find a better solution, SEM Landau black is the paint you want.  Use their adhesion promoter followed by the Landau black.  Spray in light mist coats.  It will look very good and hard to tell that it's been painted.

Here are my A-pillar trim pieces.  One has been sprayed with Landau black and the other has not.

Agreed, Scrub all you want but in the end SEM Landau Black is the best solution... Mist on light coats...

I suppose it depends on how bad the panels are.  Scrub with your favorite all purpose cleaner (Meguiars APC or Optimum Power Clean) and a soft bristle brush.  Then I like to top coat with 303 Aerospace protectant.
