For me it de rigeur to wipe down every piece of boron before use, not just swab it with a brush, but to squeeze and pull it through acetone soaked tissue. I'm sure it helps, but boron seperation is still problematic for me (and apparently others.)
My latest theory is that changing humidity is the culprit. Boron is dimensionally stable, high or low humidity, but indoor balsa is not. So the difference amounts to shear forces, given enough time.
