I like the looks and sounds of the Evapo-Rust. I'd not heard of it before and just read up all about it. I wanted to make sure that it was safe for engine blocks. Sure enough. Here are the instructions on the web site for cooling systems. Looks like it shouldn't take more than overnight.

1. Drain cooling system and rinse with water.
2. Fill system with Evapo-Rust®. (Do NOT dilute.)
3. Run Engine under normal conditions, shut engine down and let sit, for a couple hours to overnight.
4. Drain system into a container for later use.
5. Flush system with water.
6. Repeat process (1-5) if necessary.
7. Fill system with proper coolant/antifreeze.

I've got my two test chemicals now. I'm going to soak one pump in vinegar and the other in Evapo-Rust and photograph them each day to see what happens and report.

Thanks for your ideas. Hope one of them work.
