[SEL] Removing calcification & scale

[Jerry Evans]

Hi All you experts,
         The cylinder head water jacket of the Wolseley "R" I'm working on 
has a pretty thick layer of scale in it and the only access is through the 
1 1/2" outlet pipe hole and the water slots below the head.

         Is there an acid or something that I can soak it in to remove this 
that will not do damage to the cast iron? Try not to mention "trade names" 
as proprietary products available in your part of the world may not 
necessarily be available here.

         What other ideas are there for doing this - I could probably boil 
it in vinegar for some time as I know that this cleans the scale out of 
kettles, taps (faucets) and shower roses but do not know how effective it 
would be on 60 odd years of scale build up in a water jacket. The engine 
comes from a part of South Africa that has what we call "brack" or "hard" 
water - this is water that has a lot of minerals and salts in it and builds 
up a layer of this scale in anything carrying the water (pipes and the like).

         I look forward to your answers.

Keep the revs up (or down)
