PS3 Removing Account From PS3

[Kurgen1975]

With my PS4 only a couple of weeks away, i'm selling the PS3 and need to clear off my gamertag and all account details before it goes, but can't find an easy way to do this. Can anyone point me in the right direction?

Thanks

I know there's a way to set your ps3 back to it's factory settings, but it's been so long wince i did it, i can't remember where it is. It'd probably come right up on a Google search
.

Deactivate it first then go to settings>storage.
