An idiot subcontractor decided that instead of using the glue we supplied, it would be quicker to
use cyanoacrylate to fix an internal part on a 1 metre long x 40mm dia custom polycarb LED fixture
tube. All 200 of them...

We now have a very visible patch of white haze in the centre of the inside of the tubes.

I've tried some RS cyano debonder I had to hand, which does appear to make a fairly good job of
removing it, but we will need something resembling a 2 foot long cotton-bud to get to it....

Just wondering if there were any other magic tricks (apart from using low-bloom cyano!), or
particularly good brands of debonder that anyone has found to remove the bloom.... something that
doesn't need wiping off to leave a reasonably transparent finish would be particurlarly good due to
the access issues....
