Cleaning fabric, center console, armrests

Our 2007 has a grey interior and the cloth on the front door armrests and the center console lid have developed black edges. It looks a lot like the first picture here:



Further down in that thread people suggest using a Bissell steam cleaner. Well, I don't have one of those, but I do have one of those steam generators which are used for removing wall paper. I could hold it at a distance but worry that even that will be "too much".

Also, is there an easy way to take the fabric part off the console lid and the armrests? (In such a way that it can be put back on again!) Tons of steam won't hurt fabric usually, but it could melt the plastic parts of the lid underneath.

Thanks.
