Redaction in Adobe Acrobat 9 Pro

I am using Adobe Acrobat 9 Pro. I wish to redact documents to irreversibly remove selected text and meta-data, to produce a "what you see is what you get" document. I have read that a "sanitize" function is available on newer versions of Acrobat. Is there something similar to the Sanitize function in v9, or alternatively is there a series of steps which can be taken in v9 which would achieve equivalent results to the sanitize function?
