Wiping the RAV Clean

That’s the thing I’ve been thinking about since the hood latch- wiping the RAV clean.

With scientific testing getting exponentially more sophisticated, would it be POSSIBLE to wipe the RAV down without detection?

If it’s possible to discover the ratio of road grime/pollen isn’t quantitatively in line with what should be there, wouldn’t it be possible to discover fibers etc or chemical compounds from cleaning supplies that didn’t exist 12 years ago?
