[Histonet] CAP GEN.41770 Glassware cleaning

[Clare Thornton]

This checklist question has a sample procedure for how to check for residual detergent in glassware.  The procedure says to use a pH meter.  We've always used pH paper.  However, in reading their recommended procedure, you need to look for a change of greater than 0.2 pH units between source water and glassware pH.  Does anyone else use pH paper vs. a pH meter?  We only use our pH meter very infrequently and will calibrate it just prior to use.  If we use it for glassware cleaning, we'll have to calibrate more regularly, something I'd just as soon avoid if possible.  We've never had a problem with our glassware cleaning procedure with CAP in the past.  Any advice?
