I have used straight muriatic acid many times on water jacket scale and have never had problems. Let it soak for 6 hours and then rinse with baking soda and water. The acid is not strong enough to affect the iron in that short of time.

I don't mean to sound silly but go to the local dollar store and get a bottle of The Works toilet bowl cleaner. It removes hard water stains and removes globs built up inside stuff. I soak all the screens from our sinks in it and in 10 minutes the screen is clean.Shower heads,chunks fall out after being soaked. Just flush it out good with fresh water when clean.

I will agree with Bill Hazzard. Some of our ranch wells were very bad for scale in the hopper, so we would use the acid in several IH LA and LBs a year. I never saw any harm to an engine. As to the inside of a steel building and all the tools, however, there is a different story-don't ask how we learned to do it outside!

Try a plumbing supply. Products like CLR will remove rust and lime scale, and not harm the metal. Any good boiler de-scaling product should work. Just be sure to flush well after use!

Currently i have some cider vinegar sitting in there, we'll see what it does. If that doesn't work to my liking, i'll try some of the big guns suggested and i'll report back with results!

I'd forgotten about CLR. It also uses organic acids (along with some other chemicals) - and it does work really well.

Pickling vinegar is 9% acetic acid, whereas regular white vinegar is 5%, I use the pickling vinegar for de-rusting all the time, just remember to neutralize with baking soda or it WILL rust again. Concentrated acetic acid used to be available at photography suppliers, no idea where you'd find it today, maybe Amazon

As for cleaning out the water passages, a pressure washer will help flush out the passages in the head and cylinder, once the material is softened. Be sure to wear eye protection, gloves, and wear long sleeves.
