Homemade Flux Remover

I was inspired by a video by Jeri Ellsworth that showed her using homemade flux remover. This is super simple a combo of alcohol and acetone. In this video, I use a 50/50 combo of the two. So that’s 32 oz. of flux remover for $3. I Googled flux remover and it ranges from $10 to $25 for 12 oz. So that a savings of at least about $70. I have been using this on about every board I can find and it has worked great on all of them. I heart saving money. 🙂

  1. I use little spray bottles from the beauty supply store. Spray w/alcohol, scrub with toothbrush, dry with compressed air, spray/scrub with windex (to remove last bits of alcohol residue) then compressed air again.

  2. Why do you need the acetone? For years I have used straight denatured alcohol and it worked fine. Does the acetone just make it more agressive? Also, does this mixture leave no residue?

    Another helpful hint, instead of a cotton swab, use an old toothbrush with the solvent for cleaning flux off boards. It makes cleaning around the component pins and cleaning larger areas very quick and easy.

    • I’m not sure what the acetone does really, this is my first attempt. I got the recipe from Jeri Ellsworth, and it works great! I have used a toothbrush, but sometimes it spreads around more than it removes. But I still use one once in a while.
