I do a bit of occasional soldering on both large and small projects. If you properly tin your iron and wires and cover them in a small amount of flux, this flux generally does the job. It's easy to clean up, doesn't smell horrible and generally works.

As can be seen in the pic, the container might not come completely full (or maybe that's just my pessimism speaking). Still, the paste did make a great combo with the soldering wick I was using. I got the 2 oz. container, and at first glance, it does not seem like much; More so, when there's a chunk of paste missing. However, I realized during my small project that a little bit went a long way. I'm using the paste, along with a few other soldering materials, on some small PCBs. The paste seems good so far. Also, according to the labeling it should be Lead-Free, water-soluble, Non-Toxic, and Non-Acidic.

I rarely write reviews but i was so happy about this product i had to, I didn't know whether or not this flux* would work for electrical wires but i tried it anyways, it has no odor at all when you apply heat( at room temp it kinda smells like a mint chap stick(but dont use it on your lips!), it seems to be non-toxic like the packaging says it is, its extremely cheap compared to other brands i seen on amazon, i definitely will buy this again after i run out, which isn't going to be for a long time since it comes with so much! It's such a relief finding a solder than doesn't make you feel like you're getting toxic fumes pumped in your face. SO HAPPY! ( the photos are from start to finish of how it beads on to the wire)

Good product

Dried out because I left the lid off, it became very crumbly and hard to use.
The solution was to stir in vaseline until it was nice and sticky again.
