How do you handle defective PCB with flux residue?

We feel a little disappointed about the batch of goods from oversea suppliers. Some of PCB has flux residue. How should I handle them?

Clean them by yourself if it is a small batch. Inform your supplier of this disappointing situation. Argue for any remedial measures from them. Consider using a new supplier with a great quality level next time.
If there is a large amount. Ask for a refund or replace the defective goods.

What Others Are Asking

Why are there swirls or zig-zag lines on the PCB samples?

I send my PCB design to manufacturer for prototype, but they send back deviated PCB samples with additional zig-zag. Why are there zig-zag lines on it? Reducing interference?

How can I minimize the moisture adsorption on FR4 PCB?

Although the adsorption of moisture by FR4 is quite low, what is the best way to minimize it or eliminate it completely?

Why are there no BGA chips with triangular tessellation of circular pads?

A triangular tiling would allow π⁄√12 or 90.69% of the footprint to be reserved for the solder balls and the surrounding clearance, while the ubiquitous square tiling only allows π/4 or 78.54% of the footprint to be used. Why are there no BGA chips with triangular tessellation?
