Good quality
Used on small copper sculptures...applied with a small brush. Good coverage and allows solder.to flow.so much better

good flux
Really good stuff, cleans the metal well for soft soldering. East to fit parts. good value for money, not particularly sticky, but runs well into joints, Would recommend.

Excellent flux – clean, effective, and easy to use
I’ve used quite a few different soldering fluxes over the years, and this Liquid Solder Flux (30 ml) is one of the better ones I’ve come across. It works exactly as advertised and makes soldering much smoother, especially on small electronic components. The “no clean” formula is a big plus. It leaves very minimal residue, and what little remains isn’t sticky or messy. For most jobs, I don’t even need to clean the board afterwards, which saves time and effort. Application is easy thanks to the liquid consistency—it flows well into tight spaces and helps the solder spread evenly. I’ve noticed significantly improved wetting and fewer dry joints since using it. It’s especially useful for delicate electronics work where precision matters. Another advantage is that it doesn’t have an overpowering smell like some other fluxes. Also, being lead-free gives a bit of extra peace of mind. The 30 ml bottle lasts quite a long time as you only need a small amount per job, so it’s good value for money. Overall, a reliable, high-quality flux that I’d happily recommend to both beginners and experienced users.

Abit shocked at the size of the bottle for £14! My own fault for not looking at the description properly lol but looking forward to testing it out and seeing how good it works 😊

It’s just what I have been looking for, for a very long time. Perfect for my use and easy to use.

Huge fan of this flux, because it is easy to apply where you want it and very effective in improving flow and adhesion. I get really clean joints that flow so easily with this flux. It says it's "no clean," and I think that's a bit of a stretch, but it does clean up pretty easily, especially compared to other fluxes I've used. Also, it lasts a long time. I've used it on every joint (and there have been a lot of joints) for a couple of months now, and I'm maybe 1/6 of the way through the bottle. Plus, it's a Guatemalan company, which I appreciate. It's nice to actually have global goods in a global market, and not just all the goods coming from the same city in the same country (no shade, Shenzhen).

Excellent product for clean soldering, worth the cost

This flux worked great for soldering lugs and helped the solder bond well. The needle applicator is convenient, and the thin rosin flows nicely, making it easy to apply. While it requires a bit more cleaning than clear no-clean flux, it performs exceptionally well. Getting back into electronics after a long break, I've found this to be much better than the paste flux I used before. The bottle makes application easy, and you don't need much. This is a great addition to any electronics bench, and highly recommended for its affordability and effectiveness.

Probablemente un buen producto pero llegó en mal estado, la tapa no estaba bien cerrada y había una fuga en el embalaje. Espero novelas…

No smoke, Clean, good results, the only thing bad it’s a little bit sticky but with alcohol 95% problem solve
