The salt precipitate will have no effect.

The safety gap electrode tips MUST have a reasonably large radius of
curvature to prevent premature arcing.  Bending a wire Jacobs-Ladder
style won't work because the radius is is still that of the wire itself.
You need to use some carriage bolt heads, spoons, or small spheres.
