I know this isn't exactly an electronics question, but it does pertain to soldering, so I thought I'd give asking this question a shot.
So I found this bottle of sta-flow concentrated liquid starch and read the ingredients on the back. I was interested to find that it contained borax among other things that don't really pertain to flux as far as I know (corn starch, processing aids, preservative, ironing aid, and perfume). My question is can I possibly use this as a fluxing agent for brazing and/or soldering? And if not as a standalone product, how about if I were to add zinc chloride and some hydrochloric acid?
Edit 1: From what I read the ironing aid is made from some kind of lubricant such as sulfonated castor oil.
Edit 2: I apologize. I should have been more specific with what I was planning to solder/braze. I'm trying to join two copper pipes together. I figured that pure borax wouldn't work for soldering, but I do remember people talking about using borax and water as a makeshift flux for brazing, which is why I was asking.
