    Must have

    I had a plumbing repair some years ago and the hardware store recommended this flux. And it worked beautifully! So now I’m doing a plumbing job for a friend of mine and all out of the Ruby fluid So I buy flux,, no good! Doesn’t work well at all. So I by a different kind, again, no good. I’m so frustrated with all the new flux. So I go online and buy the Ruby fluid. Works perfect!!!!! I also bought the Ruby fluid liquid to use on soldering stained glass windows

    BEST CLEANING FLUX

    This is the best cleaning flux I have ever used. Don't skip and buy the cheap stuff. This will last forever and beats any other flux I have ever used. It makes the solder magical.

    RubyFluid is the 💣!

    This product has been around for over 60 years. I have used it since I was in high school. It is the best flux for conventional electronic soldering. For me this tin will last me the rest of my life.

    Simple to use, should last a very long time

    I got perfect solder joints using this to prep nichrome wire for attaching to copper wire.
