Acid stage not working..this may be of interest

I just pulled up the msds for the main frier cleaner used by restaurants. Seems that the main component is hydroxyacetic acid...basically a form of strong vinegar. It would conceivably cause an artificially high titration. It is 100% soluable
in water and boils out at 212 degrees. I dont know how one would determine before hand it its an issue. Maybe one of the forum experts can advise?

Do a shakemup test on some oil (water+oil+shake hard). Titrate before and after. if your titration goes down, then it's inflating the titration number. dry the oil before titrating a second time.

hmm...according to this website it aids in estefication and is used as a chemical peel. So we can make bio while looking younger. here

Rick, would you suggest doing the shake test on the oil, then drain the water, shake some more until the titration stops dropping to get the real titration number?
I have had some oil that titrated at 15 after drying, but the acid still had no effect on. Leading me to believe that something is neutralizing the acid.

That sounds like a plan. Just make sure the oil is dry before titrating or it could throw it off.

A titration of 15 is a lot to contribute completely to water soluble acids.
