great cleaner/flux for stainless steel soldering, enough to last a lifetime!

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!

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.

Worked great good stuff

makes soldering stainless steel easy and simple..... be sure to clean off soldered surface with baking soda or else it will rust

The flux works great it is a very thin liquid. Not thick at all and goes on nicely
