It was experience. When the manufacturers began adding the bitterant, I
began having issues with the glass film carrier for my Nikon LS-8000ED
scanner, I would clean all the glass surfaces with alcohol then blow off
the remaining dust with canned air and there would be tiny dots of
chemical residue on the glass!
Once I switched to the plain, non-bitter version in the link I sent
before, the problem went away completely. It is worth the money, even if
it does turn out to be more expensive. If the stuff were $100 a can, I’d
still buy it.
