Disclaimer; Must be true I read it on the internet ref. A. Lincoln.
I have successfully used an oxalic acid to clean solder corrosion at the tube ends. It was a 2 part; part A was a cleaner and part B a neutralizer. That 25 years ago; fixed the coolant flow and improved the running temperature. Definitely not recommended for aluminum components and no longer available at Autozone or Advance Auto. At the time I could visually confirm the effectiveness of the treatment.
Here is a nice explanation of corrosion inhibitors

There are references to using muriatic acid (hydrochloric acid) to clean cooling system. I would NOT try this venue unless it is a "nothing left to lose" and not under any circumstance with aluminum.
