Mine is all solid, and I just keep the humidity in check and wipe off dust and smudges with a dry cloth. Define "cleaning the body".
If you mean cleaning as in wiping the body down, no.

Dirty and smudgy guitars = </3

No. You clean a guitar to A. make it look pretty and B. remove all the oils, minerals, and other gunk that will hurt the finish of the guitar. This has nothing to do with the wood.
