I need your ideas on how to test flux!

Bucket of Flux Paste

I have been thinking about an episode that compares different types of flux. Primarily I want to compare rosen, water-soluble, and no clean.

I need your help with at least two aspects.

First, what to cover. The two key areas I am thinking about are how effective are each and how difficult are they to clean? Are there any other areas we should explore?

Second, how to do the testing. My thought was to sand the finish off some scrap PCBs and expose them to moisture to generate some corrosion. Is there another way to simulate joints that require cleaning? Maybe an additional test needs to be soldering new components/PCBs for comparison?

Ultimately, I can solder parts to those PCBs and then compare the resulting solder joints with a microscope.

I'm open to the community's thoughts on what to test and how. So let me know what you think!
