"Pink" background in PDFs - how to eliminate?

I'm dealing with a bunch of edited/updated PDFs and when I open them in Adobe Reader, I see white boxes over very subtle pink background, which I assume has sometihng to do with the transparency grid.

I've opened them in Photoshop and flattened them, and saved them out again as PDFs, and the 'pink' goes away, but then the file size becomes huge (187 kb file ends up being a 1.23 MB PDF when processed thru Photoshop).

I've tried all sorts of tools and searched all over for a solution to this problem - All I want is a plain white background, not white boxes on pink. Can anyone help?

Is there a setting when saving from Acrobat that will eliminate this problem, or an easy process (batch preferable as I have a lot of files to fix) that can help?

I've attached a couple of sample files, one which exhibits this "problem".and another post-Pjotoshop processing.

In Reader, if you go to preferences and select "Show Transparency Grid" in the page display preferences, a checkboard background appears which maps perfectly with the pink areas.

Interestingly enough, this problem doesn't appear on all PCs we've tested this on. I think it has to do with hardware issues perhaps (improper setup of monitors, for example), but I'm looking for a universal solution.

I don't see the pink background when I load the file. Is it possible that it has to do with color management, and how the monitors are calibrated (or not)? My monitor is color calibrated, so I would not expect to see any problems that would be cause by a miscalibrated monitor.
How was the file created?

One option would be to make sure that every page has a white background, so that you never see the "transparent" background. Depending on how the file was originally created, you can either do this in the original application, or you would modify the files after they were created with other tools. So again, how did you create this file?

And, which version of Acrobat are you using?

If you have at least Acrobat 8, try the following: Select Document>Background>Add/Replace, then select white as the background color in the "Source" area - set From color to white. After you do that, you should not see any of the "transparent" areas anymore.

With Acrobat 7 you would need to create a one page PDF file that contains only white background (you could do that in Photoshop) and then use that as your background image.
