In your other post you wrote the black tank flush was not in use and the toilet overflowed. It makes a difference in the cleanup depending on which situation occurred.
I suspect you have a Thetford toilet which is known to not close the water valve and fill the bowl. The overflow then is clean water and much easier to clean up and dry out. In this case, I would remove everything from the passthru compartment, dry it up as best as possible and then use fans or a dehumidifier to finish it off. I also recommend you replace the Thetford with a Dometic 310/320 toilet otherwise you will get to do this again. Lots of posts here on that overflow problem.
