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

Excellent solder flux. Works as it should and requires little to no need for cleanup after use.

Excellent product for model train building electronics. The needle pipe is great for pin pointing your exact location to apply Kester. I use my in a small cap with a brush, but it evaporates very quickly. Does not leave any residue, does not have a foul odor when heated.

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!

The bottle is labeled with the date of manufacture and expiration date. The applicator is awesome. This is actually brilliant for majority of users as buying larger volumes would be a waste for many people. This flux dries out very fast from the iron's heat. It does work though.

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

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!

Best customer service! Also the best high flow liquid flux! Been using it for a decade!

Worst flux I've ever used. Doesn't work at all
