Idk bit why not just use clock work mod?

 

Okay can't argue with that (successfully)

Have you tried to confirm the files have been removed with a file explorer (astro, es file explorer)?

 

Did you try my suggestion? Does the app work?

 

The idea of it sounds good. Sounds as if it should. Unless it causes sever damage I sermon reason not to try it.

 

Alsaces, you have a good point but if i may. With a good nandroid backup one would have nothing to fear.

 

I always use Apps2sd. It has an indication of how much was cleared. The pro version has a widget-I havent tried that

 

I use ES Task Manager to clear the cache on mine
