[Histonet] Reference for the use of Bromsulphalein or BSP for celaning of glassware

[Smallwood, Lorraine]

Hello Histonetters!  Several months ago someone had posted a reference for the use of bromsulphalein in cleaning of lab glassware.  I went to the Histonet archives but I cannot find it.  Could someone please provide this information again?  I am in need of this information for a reference for the procedure for an upcoming inspection.  
As always, you guys are the greatest!!
Thanks!
Lorraine
