Question for Squirrel the Lurker

Your post on alodine and using boxes to dip wing skins brings up another
question. First, here's a quote from your most excellent post:

I dip all that I can (1 gallon will allow me to dip wing skins). I use
shallow cardboard boxes (Van's boxes from the tail kit is just great), and
line them with 6 mil polyethylene (construction vapour barrier). One for
etch, another for rinse, and a final one for chromic acid. Finally rinse the
part well before letting dry. Parts look really nice when dipped (did I say
that once too many?). [close quote]

How do you retrieve the alodine and phosphoric acid dips? Or do you
dispose of them once you are finished with the polyethylene-lined box? I
guess you could keep the box elevated, like on a table, and tip it over at a
corner and funnel the juice back into a container.

Thanks.

Larry lots of alodining to do Smith
