Is the “Cleanup” tool secure enough to be used for redaction?

I was thinking of using Adobe Scan to scan my W-2 and send it as proof of employment, however I need to redact my SSN and some other things. Is the "Cleanup" tool in the Adobe Scan app secure enough to be used for redaction? Or does the tool simply overlay a layer which could be removed by a malicious party?

Hopefully someone at Adobe can answer this one for me. Thanks!
