I'd strongly advocate for what I call "The Boy Scout Campsite Approach to Code Improvement". Boy Scouts have a motto "Leave the Campsite Better than You Found It". What I'd do is:

* Pair program to teach people you work with that there is another way; they may simply not know any better. * Make any code you touch better; new / old it doesn't make any difference. Do it right. * Important: NEVER, EVER COMPROMISE ON THIS!!! Seriously you skip one time and it can all be downhill after that (sayeth the voice of regretted experience).
