Hi Mike! This is more of a question than a statement but would not polyurethane particles char/burn/decompose if immersed in the wave solderpot and end up being a constituent of the solderpot dross? I couldn't find the char/flame resistance values for polyurethane but I am guessing that they would not survive long in the solderpot (typical solderpot temperature = 500F).

And in turn, a method to remove this sort of contamination???
