    You have to do a Clean Install of either OS X 10.8 Mountain Lion do get to OS X 10.8 Mountain Lion or if you want to start fresh with OS X 10.9 Mavericks, you have to do a Clean Install of that.

    Redownload ML from the App Store and do not start the install. Now use this free app along with a 8GB USB key to make a ML installer. Then option key boot to the USB installer.

    Once the recovery screen comes up launch Disk Utility and select the drive brand name at the very top of the list (above Macintosh HD) and erase the entire disk to Mac OS Extended (Journaled). Now quit Disk Util and install the OS.

    Look into your Applications folder for a file called "Install Mountain Lion".
    The rest should be done via the Weaselboy linked to. And there are plenty of guides out there on how to do a clean install of OS X 10.8 Mountain Lion.

    Yes you can use a DVD. Just follow this.

    Diskmaker X will also make a DVD, but I think it might require a dual layer, where the other process does not.

    That makes it even easier. Do a command-option-r boot (hold all three at once). You will enter your wifi PW then you will see a spinning globe while the recovery utility downloads.

    Then you will get this screen.

    Launch Disk Util and select the drive brand name at the very top and erase the entire disk to Mac OS Extended (Journaled). By selected the disk itself and not just Macintosh HD, you are also erasing the Mavs recovery partition along with everything on the drive.

    Then quit Disk Util and click Reinstall OS. That will DL and install Mountain Lion that came with your system.

    Internet Recovery like this will always get you back to whatever came from the factory.

    It is not for sale any longer in the App Store. If you previously purchased ML, it will still be in your purchases list. If you never purchased it and now wish to, you can buy it from Apple here for $19.99. They will email you a code you can redeem in the App Store to download Mountain Lion.

    I'm not sure, but when you erase your partition, I think you may want to create new partition with same name for time machine restore when whichever OS you chose is finished.

    Clean install seems to be the way to go. I wish apple would test their os pass the install process, like actually use it to see the issues before releasing.
