Kester979 Soldering Flux Bottle by TekLine 2oz Water Based No-Clean

I typically use the Kester pen applicators, but decided to try this bottle instead. It is much easier to apply the right amount of flux in the right place with the needle applicator supplied with this flux. The pens tend to deliver too much or not enough since you have to pump them a couple times to wet the felt tip end.This bottle is not cheap and has an expiration date so be aware of that and make sure you will be able to use it before the expiration date. There is a lot of product in the bottle.

A hair less watery than 951, which is good. Doesn't leave a bunch of white residue like 951, which is great. But I still rinse my PCBs after soldering with a mineral spirits based tar remover, and then water, which leaves them gleaming.
