On my phone so I can't dig out links, but there are two tools being recommended: Redact and PowerDeleteSuite. Both allow you to edit the comment/post before deleting, because if you straight-up delete the message Reddit reserves the right to the message content as it stood at deletion.
Good point about deleting or edit your comments before deleting the post, I initially started by going through mine manually before using Redact and a few slipped through the net.
