The "Glassware Cleaning" section of any of Anatel's stock SOP's describes a
laboratory detergent/hydrogen peroxide cleaning sequence that works very well
in practical use. Anatel also recommends chromic acid for recalcitrant items
(yeah, I know - when there's a better alternative I'll use it, too), and I have
always required this step for new glassware or glassware with uncertain
Good document source is: www.anatel.com, and a good SOP example is available
at www.anatel.com/pdf/A1Ksop1001.pdf, "Glassware Cleaning".
NOW; once those flasks are clean, DEDICATE THEM, and store them carefully
(covering the mouth of each flask with foil helps)! It is much easier than
pursuing a failure investigation every time someone from the QC lab borrows a piece
of glassware and cleans it to "laboratory standards".
