<< ray at sirius.com: The acetic acid supposedly sterilizes the solution,
killing all the germs. We want to 
make it with citric acid, at a dilution of 1 gm per 100 gm water. It's
just the protein 
and the acid in the solution. 

Here's the question: Will the citric acid kill germs as well as the acetic
acid? (Sorry 
about the highly technical language... I hope you know what I mean.)


(Even the acetic does not really sterilize.)

No citric acid will not work as well.  If you would like a copy of my two
