AFAIK, Berryman doesn't make any of the Autozone branded chemicals. When I worked for AZ many moons ago, the carb cleaner was made by a company in Florida called Petro Chemical. Petro was purchased by a company called Amrep a few years back.
AZ's carb cleaner is decent, IMO. I used a can to spray off an engine after I had degreased and rinsed it. The methanol got the water into solution with the acetone and toluene, and made it evaporate so that no rust formed. I painted it shortly thereafter with good results.
