Just use CCleaner one or two times per month and you are gucci. This is for a normal user, if you are a more intensive user: lots of programs, creating files and copying pasting files etc you will want to use ccleaner at least 1 time per week!
Other thing is you need to format your PC one time per year and clean its fans if you are a normal user. If you are a more intensive one you should clean it 2 time per year and format it 2 or 3 times a year!
