RE: Acid cleaning glassware

From:"Luck, Greg D."


I concur with Priscilla (in Wyoming).  We've been using a 50% solution of
12.5% commercial sodium hypochlorite for almost 10 years and it works very
well.  We used to use potassium dichromate but discovered that was overkill.
Thanks, Greg

Happy New Year to all in Histoland - thought I would reply to
discussion on acid clean glassware.  I have found that 10% chlorox left
in a coplin jar or glassware for 30 minutes and then rinsed well in
distilled deionized water is sufficient for stains that use metals in
their formulation.  Years ago I remember making up a "nasty" 2 acid
cleaner that I am surprised didn't dissolve any thing that I put into
it (grin) It worked too, but so far the 10% chlorox does the job for me
now.  There may be areas of the different countries that others are in
that the chlorox won't do as complete a cleaning, but I should think
that it would be worth a try.   Any comments?  Priscilla in Wyoming
