Review: A good product. - I wanted some flux for a plumbing job in the house. I checked the local supermarket prices but found them too expensive for the size of job I wanted to do. A quick check with desertcart and my Flux arrived. It even has a useful applicator attatched to the lid. A very useful item. The flux is very good at its job. Well worth buying.

## Questions & Answers

**Q: Is this flux suitable for soldering copper foiled stained glass items and art? I would appreciate your advise.**
A: I have not used it for such and in the past when soldering copper foil around glass I have always found it best to use pre-fluxed solder because it enables one to limit the soldered area.  LO CO is a messy flux to manage

**Q: is it an acid flux**
A: The product does not seem to be acid base material. I tell what it works very indeed and have no complaints

**Q: Is this okay to soldering mobile and other devices?**
A: I think you'd struggle to apply it on microchips/ electronic circuits. This is aimed at plumbing pipework. For PCB and electronic work I would advise looking for a flux 'pen' applicator...this is FAR too thick for what you're looking for.

**Q: Is this flux suitable for brazing**
A: No, it is the wrong kind, check out  " how to brew by John Palmer"  for chapter and verse.

### ⭐⭐⭐⭐⭐ Good flux paste
*by A***B on 17 July 2025*

Absolutely brilliant

### ⭐⭐⭐⭐ Excellent Soldering Paste - Applicator?
*by M***M on 2 September 2020*

First off the actual paste is probably the best soldering paste I've used for general purpose soldering. It seems to very quickly wick into any joint faster than most and really helps draw in the solder. What I didn't like was the brush applicator which, when pulled out of the tub is just a big gloopy mass because of course it's jammed right into the paste. This means small applications are impossible near enough. To be honest I'd rather there was no brush at all. However, because of the quality of the paste this is a five star product dropping a star for the awkward brush applicator.
