I don't do anything out of the norm, it doesn't need to be spotless anyway, just tidy but lived in, they are there mainly to make sure 1, there are no extra people 2, you haven't put holes in the way and 3, it isn't "dirty".

I'm sure whoever is doing the inspection probably wont give it a second thought :P

But having said that, I can't wait to be back in our own place next year! We've been renting the last couple of years because we've moved 4 times in 2 years and I HATE it!
