kodm If by local you're referring to language files, then Bleachbit will do the trick. Check the tutorial forum for a tutorial post I created for doing so; Tools to Keep Your Drive Free of Detritus.
@Josh: How does Bleachbit cause breakage if you are merely removing language files? FTR, I've not experienced any issues using Bleachbit under Solus or Debian, including the removal of language files that I'll never need or use.
