Removal of flux

[MrTube]

We use Quickbraid all the time here, it's a normal consumer product.
However, I highly doubt rosin soldering braid will do anything to a silver soldered product. You silver solder at 1400+F not 650. I think when I solder using Stay-Silv 15 I'm over 1600F. The nice thing about Stay-Silv 15 is for copper to copper joints you don't use a flux.

I've also never seen it remove flux but could be wrong there.
