I am currently having the top section of the door panels and the speaker housing/door pocket sections covered in "Stratos" leather .... (a light grey). The arm-rests have already been done in this material and they look superb! That will only leave the middle section as original. I would like to ask for your help/advice in two directions ..... Firstly, that middle, fabric section is quite grubby and could do with a good clean. The ideal time is before refitting the leather-covered sections. Now I had thought of making a slurry of washing-up powder and applying it. I would then let it dry and brush/wash it off. It's messy, but has been effective in the past! I would like your help in suggesting any other effective cleaner, please? Maybe a proprietary product? Now, another possibility would be to cover the middle section, too, in suede? What do you think of that idea? I seem to recall someone on the A2OC having that done? Am I right? AND, someone in Germany, too? Oh well, all this stems from finding a FANTASTIC firm that does leather work! .... they did those arm-rests for just £100, all-in! I've been delighted with the work! ( Did you know that standard hides have to be thinned first, and that this action is called "skiving"?" Oh, there seems to be a potential problem with perforating the leather that will cover the speaker grills, so as to allow sound transmission? Any ideas? Thanks for your help! ..... David
