Review: Excellent flux with easy cleanup - This flux works well for soldering electrical connections. It's low odor and sticks well when applied. Solder flows and adheres well when used with this flux. I've used it on copper and steel without problems. Cleanup is easy with alcohol and a brush.
Review: Great value for money, works on copper jewelry with silver solder. - I am torch soldering copper jewelry with safety silv 45, I tried two types of fluxes before I found this one, one was 10+ years old and no good, the other was extremely overpriced from the jewelry making section of a craft store and gave the same results. I thought I was doing something wrong, until I tried this one. This works perfectly, and I can't believe how cheap it is. I was shocked that it worked, because I read somewhere on here that it wasn't for silver, but it worked just fine with my silver solder on copper. It makes the metal flow right into place. Be sure to wash it off of any copper it comes into contact with when you are done. I made the mistake of getting it on one of my copper bracelets as I was working and didn't notice untill hours later, now it needs a good cleaning and polishing. Attached is an image of a ring I soldered using this, the metal flowed right into the cracks where it is supposed to be and the joint can barely be seen.
