Not to discount what you have said as they are all very valid points, but Pickling lime is not sodium hydroxide (NaOH). NaOH is a drain cleaner. it is currently being used to regenerate GFO by some folks. (i plan to try this weekend).

Quoted Direclty from the Mrs. Wages page
Pickling lime is food grade calcium hydroxide with no additives or preservatives

Ha! Your right! I am getting old! 43 and my memory escapes me. LOL
