Thanks.
This wound up a multi-million dollar medical malpractice lawsuit years ago. The manufacturer of some artificial joints (hip, femur ball) used chemical wash to sterilize them, and they were inserted in the patient without secondary inspection (supplied in sealed, single use packaging). Yes, the cleaning fluid was still there, and infected the wound - the whole thing had to be done over again, in some cases the patients suffered permanent disability.
Yes, I believe the lawsuit you are talking about is the one where the spec said to ultrasonic clean them and they didn't. They saved $1 per part. It's hard to believe that invisible oil can cause such a problem but then the glue wouldn't stick. Made those peoples lives miserable.
