## Questions & Answers

**Q: where can we get msds and tds on this item - flux 951?**
A: You would need to contact the flux manufacturer on that.

**Q: Will it work with soldering aluminum?**
A: We do not think so. Aluminum requires any oxidation to be removed before processes such as welding. I do not know of any process for soldering aluminum. And this flux will not work.

**Q: What's the difference between this & 186  cleaner??**
A: Kester 951 is a liquid no-clean flux that is designed for soldering of conventional and surface mount circuit board assemblies. The extremely low solids content and activator system results in virtually no residue left on the assembly after soldering. 
Kester 186 is a rosin-based organic flux that is specifically designed for rework of conventional and surface mount circuit board assemblies. The low solids content and activator system results in LOW RESIDUE left on the assembly after soldering.

**Q: Does this item come with certificates of conformance from kester?  what is the expiration date on current stock?**
A: I dont recall getting a certificate of conformance, but I can tell you it works without incident on the small electronic sound wiring I use it on. The bottle has a DOM of 6/9/2021 and DOE of 6/9/22

## Customer Reviews

### ⭐⭐⭐⭐⭐ Excellent
*by J***. on November 12, 2025*

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

### ⭐⭐⭐⭐⭐ Evaporates very quickly
*by B***D on January 7, 2022*

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.

### ⭐⭐⭐⭐⭐ A mess free, trouble free, easy to use solution for hobbiest and professionals
*by A***. on February 13, 2025*

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!
