Removing flux?

I'm doing some brazing and would like to remove the solid cake of
flux that forms around the braze.
How do I remove that flux?
Mechanical or is there a chemical? - Mike

In my experience, most brazing flux used with steel may be removed
with water. In the days when I did some, an old toothbrush and warm
water did the trip.

What flux are you using? The manufacturer (well, name on the jar)
probably has cleanup procedures.

I see where it says to quence in hot water; I"ll give it a try - MIke

Quenching is how it is to be rapidly cooled. Look again to see if there is
anything about cleanup and inspection after the weld.

I'll be following this thread. In 40 years of welding and brazing,
I've never found a GOOD way to remove the glass-like residue from
brazing flux. At one place I worked, they used bare (unfluxed) rod,
and had a flux pot between the Acetylene tank and the torch.
Interesting green flame, great fluxing action, and almost zero
residue.

I'm working on the fuel system for my homebuilt and I need 1.5 psi or
less fuel pressure.
I'm thinking "remote float bowl" gravity feeding the ex Harley carb,
and either a rear floatbowl from a single-pumper Holley 4bbl
(preferably center float) or the floatbowl from an SU HS8.

Anyone on the list in east central Canada (sw ontario) have either
floating around (no pun intended)

Buy an adjustable fuel pressure regulator
which you fit UP CLOSE to the point of use.
