[Healeys] Pickling Cast Iron

[Bob Spidell]

Hi Patrick,

My first thought was a 'hot tank' like some engine shops use to clean blocks.  It's a big tank filled with a hot, 
alkaline solution (I believe made with NaOH, aka lye).  I did some googling to confirm and came across this:

I don't know if hydrogen embrittlement affects cast iron, but I'd avoid anything acidic anyway.

Bob
