What is the word for "making something proper"

I am thinking along the lines of "normalize" -- something like proper-ize.

-- UPDATE --

In one of my comments, I presented an example...

a disorganized mess (for example, a cluttered desk) that I want to "make proper" by organizing things "properly"

Take the above example figuratively NOT literally. An answer like "tidy up" is not what I'm looking for.
