Hi all, just a couple of thoughts:
re separating the de from the acid wash - why bother, you haven't used all the acid, put a lid on it, put it outside and use it again when you need to wash again - why waste a perfectly good acid wash?
re 1:1 solution, ! That sounds about 4x too strong. The 'e' clips and plastic parts (the 'ribs etc) can start to deteriorate from too much acid.

BTW, it seems that chemically cleaning them every year or two helps preserve them, be it an acid wash or a TSP/ oxyclean dip. I'll be interested to see what else gets posted here.
