Hey all, need some brainthoughts on this.

Went to look at a car today, and it mostly looks good. Pending a test drive and maybe a PPI, I'll likely make an offer. But the thing that concerned me most was what looked like spilled coca cola or something in the back under-spare area. Can anyone tell what this might be? I don't believe it's corrosion or anything - one spot I touched was sticky.

Is this anything that might make you think twice about a car? Any thoughts on a course of action? Just use a wet rag? Can this stuff all be safely unscrewed and moved out of the way to clean?

Thanks, as always.
