Great flux
This flux is really amazing. Allows you to solder stainless steel which is usually very hard to do. I am using it for copper foil too, as I am a stained glass artist and it works well. One thing is that you must have good ventilation when using this, it smokes and creates a very acrid smell which I am sure is not safe to breathe!

The item has a good substance combination to work as described, and it works fine. It may contain hydrochloric acid, HCL; therefore, do not breathe the fume.

Excellent Flux
I bought this flux to solder stainless steel BBQ skewers which I cut and fashioned into what you see in the picture. I had never soldered before and read that solding stainless steel was difficult and a special acidic flux was necessary. I was able to turn BBQ skewers into these geometric shapes for a wedding. I must say that there was a definite learning curve and the flux was a MUST to get the solder to flow but once I got the hang of it,it was a breeze. I HIGHLY recommend this stuff if you are soldering stainless steel. Beyond that I have no knowledge or experiences with soldering. As others have said YOU MUST WASH IT OFF AFTER or it is corrosive. I washed with mild dish detergent and thoroughly dried each shape (72) and had no problems. Another note, the bottle did swell and I had to loosen the lid after a few days. As I said I know nothing about soldering other than what I made so good luck. I couldn't get the solder to stick or flow without this stuff so I have to say it's a definite buy!
