Swiffers & MF's are great if the dirt isn't embedded in the crevices that are often present on center consoles - around buttons, shifter boots, ash trays, etc.
To clean those crevices, I have a very soft 100% camel hair paint brush that I cut all but 1" of the bristles off. I then wrapped electrical tape around the metal part of the brush to protect from accidental scratching. I use this brush to aggetate (sp?) the crevices (dry), and then I hit 'em with the MF.
Just a suggestion that might help some more. I've never had a scratching problem with the brush - make sure you get a good one if you decide to try it (1" wide brush @ Lowes = $12).
