I’m planning on spending a week going over my X and I’m looking for advice or guidance on cleaning & preserving the underside of this fantastic automobile. My X is a 2008 with 14,000 miles that I think was driven by a smaller person, from the automatic seats, and was not driven in the rain as there is only dust on the undercarriage. At this point the only thing this car has experienced is an oil change and I can’t find even a stone chip on her! On the bare aluminum and steel casting I torn on how to clean and “preserve” the like new appearance. The last thing I want to do is to use a WD-40 and have more dust accumulate on the “sticky” surface. Most importantly I don’t want to have the part’s labels come off of the various components on the underside.
