Default Cleaning Brazing Flux

I was wondering if anybody could suggest a flux that is easy to remove. Sometimes brazing is the best means of joining/repairing something rather than welding. However trying to remove the flux can sometimes be almost impossible. Most recommend soaking the object in very hot water for a period of time. Most of the time that isn't a practical option. Any ideas would be appreciated. Thanks

Simple borax. My nephew swears by it for his blacksmithing.

I've got some 20 Mule Team Borax. I'll give that a try and see how difficult it is to remove the glassy flux after it cools.
Thanks for the suggestion.

I have a few coated rods left but my next purchase will be bare rod if I can come up with a flux that is easy to remove when the job is finished.

Bead or sand blasting removes it, don't know if it would be practical in your case.
