I`m not sure you can push this back to the factory default, however to completely remove the configuration, do the following:

Enable,

Conf t

write erase

Confirm the erase, and then reload the device via reload (do not save the configuration).

If the device has a CSC-SSM module, then theres a reset factory defaults on the menus of the module (type Session 1 from the ASA)

ASA01(config)# mode ?

configure mode commands/options:

  multiple   Multiple mode; mode with security contexts

  noconfirm  Do not prompt for confirmation

  single     Single mode; mode without security contexts

ASA01(config)# mode single

WARNING: This command will change the behavior of the device

WARNING: This command will initiate a Reboot

Proceed with change mode? [confirm]

Security context mode: single

***

*** --- SHUTDOWN NOW ---

...

ASA01(config)# int gi 0/0

ASA01(config-if)# ?

Interface configuration commands:

  authentication   authentication subcommands
