Subject: Re: Sanitizer getting old

Keith asks how to determine if his sanitizers (iodophor and Starsan)  
are still effective after a long (a year or more) of unuse. I have no  
experience with Starsan, so I'll leave that response to others.   
Regarding iodophor solutions, National Chemicals, Inc., who makes B-T- 
F Iodophor Solutions also supplies iodine test paper strips for a  
mere $1.63 for a pack of 25 strips. The strips turn shades of dark  
gray depending on the concentration of iodine in the solution. The  
color is reminiscent of a starch test, and I'm guessing the paper  
strips may be impregnated with starch. I rarely use them, as one can  
pretty well judge the iodine content of a solution by its amber  
color. You can order the test strips on the company's web site at  
nationalchemicals.com.

The contact info from their web site is:
