Remove a repeated text box in a pdf?

[JIPNET]

I have the following in a PDF (see attached screen shot) which I want to remove from 300 pages. I can manually select the blue text and delete it per page; is there a way to do this for all pages in one redaction?

The offending text is 96 pt bold font. That should be easy to spot and remove but I am not sure how using preflight. It is also using 2 process plates (Process Cyan 18%, Pr. Magenta 15%—discovered through Output Preview), but again I am not sure how to search and eliminate these.

I found it by accident: text (not font) gives you the option to specify a size; removing that through preflight did the trick.
