Could anyone out there provide any information or support to the 
following effort;



	We are trying to monitor the cleaning effectiveness of the water 
wash (2% solution of 2444 rinse aid saponifier) in our Westek cleaner.  
We are using it to clean PWB's that have been soldered using 630-20 
water soluble f

lux.

	We are measuring the solutions' PH and titration to determine the 
cleaning effectiveness of the water / rinse aid solution.  

	Can a relationship be established between the PH and the amount 
of rinse aid (titration) as to the remaining cleaning life of the 
solution? This will be used as an indicator as to when to replace the 
solution in the tank

?

	Thanks for any information or help on this subject.
