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.
