Don't know much about chemistry but I've often wondered if the sterile solutions for cleaning contact lenses might be useful at some stage in the record cleaning process. There are two 360ml bottles of Focus Care (CIBA Vision) in our house but they're for some reason from Italy. The bits I can make out say that a soaking removes protein, washes, rinses, disinfects, conserves and hydrates lenses, more or less what you want to do with your records. Stated ingredients:
"Soluzione isotonica, acquosa contente polyhexanide allo 0,0001% come principio attivo e conservante, cloruro di sodio, poloxamer 407, idrogeno fosfato disodico, edatato bisodico e fosfato sodoco diiddrogeno. Non contiene clorexidina o thimrosal."
Does that mean it has salt in it and some other things? Perhaps not so pure after all.
