The latest new tool I’m playing with today is dust me selectors from Sitepoint.com. This tool lets me find all the unused CSS selectors on my page in one click, but more than that, it can also spider an entire site keeping track of user selectors so it can tell you which are not being used anywhere. This has always been an arduous manual job in the past, keeping track of a CSS file which gets edited by multiple users is hard. Using Dust Me I was able to shave 20% off one CSS file and make the whole thing much neater, cleaner and more legible.
