Automatic way to delete caches

Hei guys,

While discussing some problem with Apple Tech Support, that guy told me that it's a good idea to clear the caches once a month.

The caches that need to be cleaned are

Finder - MacBookPro - Users - [username] - Library - caches (delete all), cookies (delete all), saved application state (delete all)

Finder - go - computer - MacBookpro - library - caches (delete all)

Empty trash after deleting all these files.

Is any automatic way available to do this? Automator or AppleScript or a Terminal command etc.

I tried Automator. But, the process failed as the admin password is required to delete those files and I couldn't insert the password entry related "Actions".

In Terminal, I could find commands to delete the entire folder. So, if I use this here, the "Caches" folder itself will be deleted whereas, my aim is to delete the folder contents.

Regards,
