My concern would be pushing the "dirty" into the PTH's.

Subject: [TN] Acetone as a cleaning agent for PCBA's

I have a customer that uses acetone to wipe down their PCBA's upon receipt.
The assemblies we make for them are cleaned using a closed loop aqueous board washer then sampled for cleanliness with our zero-ion tester per J-std-001E guidelines.
Recently this customer commented that boards appeared dirty upon cleaning with the acetone.  Does anyone have any thoughts on this acetone cleaning process.
Thanks,

Bob
