Kester 951 Liquid Soldering Flux, No-Clean, 2-ounce Bottle

It appears to be the quality no-clean flux it purports to be. Happy with my purchase.

I purchased this product at a glance and I have not regretted it. It goes on easy and cleans all soldering surfaces without making a mess. I normally go for paste, but this converted me to liquid. I don't work on electronics professionally, I'm just a humble hobbiest. As a hobbiest, I can tell you every brand of flux that works the best, that is easy to clean up etc. Kester 951 blows everything out of the water! I barely have to clean up after soldering a wire, sometimes I don't even have to. It's incredibly flammable, and that's the only con. The smell isn't so bad either, it smells pleasant when burned with an iron.I will buy this again when the time arises.The seller had it delivered a week earlier than expected, which was really awesome!

Soldering

This Flux does work well. Maybe not as good as your standard flux that needs to be cleaned up. But that's what you get for the convenience this provides. My only complaint is how quickly it evaporates even without heat applied. I've found that I've had to reapply this more often as I'm working, compared to my standard flux. Also, I'm using up a lot more of it just on small projects.So just be warned, it works well and no cleanup is needed, but it evaporates quickly. Causing you to use more of it.

Like 150 proof vodka.. cleans very well. slight odor so use ventilation. cleans well, easy applicator and it should last me a long time this liquid flux. Thanks!

This flux works great. I used it to replace a smt memory chip. It cleaned up super easy and wasn’t sticky.

Easy to clean and works well

Performs just as 951 does. It's a low solid flux that evaporates quickly and cleanly, leaving a nice finish.Unfortunately it does have a shelf life and mine arrived about halfway through that lifespan. Good on CML for labeling things properly, many repackagers wouldn't.
