Is anyone here familiar with Eco Lab's Multi Quat 146 Sanitizer and is it a viable product for sanitizing beer making equipment

Liquid; Disinfectant (Food Premises); Benzalkonium Chloride 3%; Didecyl Dimethyl Ammonium Chloride 1.35%; Dioctyl Dimethyl Ammonium Chloride 0.9%; Octyl Decyl Dimethyl Ammonium Chloride 2.25%

I, too, have access to dual-quat sanitizer at work. It is my understanding that it is not recommended for brewing purposes, but never heard why. I'm curious what everyone has to say...

Well it seems that there is not to much information about the use of Quat sanitizer in beer production so i will develop some.

Considering I do not want to potentially waste a whole batch of beer, I am going to Sanitize 4 12 oz. bottles with the Quat Sanitizer and air dry them the remaining product will be sanitized by Hot water in the dishwasher for the control group.

I will post results of the experiment when completed

Luckily my wife is a food scientist and professional taster she will beable to tell if there is even a minute difference the the two samples

Let us know your results. We use this kind of sanitizer in the food industry a lot. At least the version we use at my store, it's no-rinse, but it does need to totally dry. Never noticed a residual taste, but it does have some level of chemical odor when wet.

Well it looks like Quat Sanitizer is not a good choice,

Upon doing some research apparently the sanitizer is "Persistent" meaning even after rinsing and drying it can remain on the equipment and I would guess potentially kill the yeast.
