I am totally agree with you Rene 
I also experienced the same problem with CAP regarding Schiff's reagent storing.

الموضوع: Re: [Histonet] Schiff : room temp or not 
 
 This is another example of the ignorance level of some Joint Commission "experts" that really do not know what they are talking about.
The Schiff reagent (the "hay yellow" solution of Basic Fucsin) is temperature sensitive and HAS to be stored refrigerated or it will lose its reactivity in just a few days.

         Joint Commission told us we could not keep it in the refrigerator because the bottle said to store it at room temperature. We called the manufacturer and they faxed us a paper stating we could keep it in the fridge. However It wasn't easy to get the paper because the manufacturer prefers the shelf live to be shorter so we buy more.

>> When staining PAS's, does the Schiff need to be room temp or does it matter?  Just curious about when to add it to our Sakura stainer.  Should we put the schiff's on at the beginning of our shift so it's room temp when we need it or when should add it when we add PAS slides to it that need to be stained? Thanks!
