E85 - Z4 cleaning dash ?

[mbtech01]

can anybody tell me whats the best way to clean the black upper & lower parts of the dashboard. I have a few faint grubby marks i'd like to clean but the surface is a rough textured matt black plastic & i don't want it to end up looking shiny & polished from some silicon based products you can get. I can get hold of any of the autoglym products but maybe someone out there knows of a tried & tested product that gives good results. I've also tried some warm soapy water on a cloth but it doesn't seem to make much difference.

I use meguiars APC diluted 10:1, spray plenty on a cloth/towel (not too fibrous otherwise the lint rubs off onto the dash) and give the trim a good rub down. If you use white cloths you'll see just how much crud is lifted off. Once you've got it cleaned, treat it with some poorboys natural trim dressing. This doesn't leave any gloss so no worries on that front.
