So we were using this great flux for a really long time- Novacan's Old Master's Flux. Super effective, great flow, easy to use, yes. BUT. It was eating our fume extractors. Literally eating through the plastic. Apparently the main component in flux, zinc chloride, is corrosive to plastic.
As a result, we had to switch to using a zinc-chloride-free flux. To my research, there are only two available- GlasPro EZ40 flux (from ebay) and Studio Pro Safety Flux, found at Amazon and Hobby Lobby.
The thing you'd need to know, is that the EZ40 is sticky, like sugar syrup. Smokes a lot when heated, so good ventillation is essential for working with it (a fan blowing away from your work, and out a window is ideal.) You have to layer it on frequently while working. BUT, it leaves your solder seams shinier and brighter than I've ever seen with a zinc chloride flux.
Studio Pro's flux is more watery, so again, you'd need to just use more of it.
Giving yourself the chance to use a product, and figure it out is really key here!
