Ford Blitz Restoration/Rebuild

[Lynn Eades]

You are right Grant. It is some time back that I found a very good article in an IMPCO (gas) manual, about cleaning out cast iron engine blocks (and how important it is to do so). Now that you mention it, it is Hydrachloric.
The Muriatic acid is a certain strength of it.
That cleared the confusion in my head. I now recall the Phosphoric (in Coke, and lots of other food) is for cleaning mild steel. If you put high tensile steel, cast iron or any non ferrous metals in it, it then makes everything else you put in it, dirty. Thanks Grant.

I have met old guys, that are way off the truth. I don't think they mean to be. It just happens as our brain cells die,..... Its a shame the ones that die, don't all come from the 90% we don't use.
