I tried to use Onyx, but it requires admin priviledges just to start up, and I normally do not run as admin. The alternative I found does the same job and is slicker, IMO.

Personally don't care for Onyx.
You can go the cheap route:
- Go to Safari menu
- Select Empty Cache
- Click on the Empty button.
- Go to Safari menu
- Select Preferences
- Select the Security tab
- Press on the Show Cookies button.
- Decide to remove all or remove certain cookies.
Or the cheap and simple route:
- Go to Safari menu
- Select Reset Safari (Note, this deletes everything: Cache, Cookies, History, etc.)
OnyX is great and is just a front end to features already build into OS X one of the better tools is resetting the spotlight index, which unless you are comfortable with terminal(it's not that hard honest) makes life easier.
