Well, I've never worried too much about that, personally. The cache files are generally "recycled" automatically after a while by the system.
You can empty the Trash (Recycle Bin) by either selecting the command from the "Finder" menu (top left, in Finder) or holding down the control button and clicking on the Trash icon in the Dock (bottom, on right) and selecting "Empty Trash" from the menu.
But there are a few programs out there that can speed the process up and take care of that kind of thing. I ran a quick search for you -- here's the results:

I actually press Ctrl while clicking the Trash Bin to empty it. I saw something that clears the cache somewhere... is that similar to Disk Cleanup?
