I just saw in a flier that Mirka offers an Abranet belt sander belt.
Anybody tried them yet?
When I do drawers, I belt sand the dovetails to get them flat, I also smear a bit of glue into the joint before sanding to fill any gaps that might be present, as a consequence, the belts load up pretty quickly. I know this won't solve that, but it might make blowing the glue off of the belt with compressed air a bit more productive.
