Wiping medical implants after passivation
1996
Hello, I am currently working for a company that designs and manufactures medical bone implants made of 316 Stainless Steel. The implants are buffed, electropolished, measured, passivated and inspected.
As part of the Q.A. department, I am interested in the "cloth" that we should be using to properly wipe these parts after passivating, so as not to scratch them. We are currently using "paper towel" which I believe to be detrimental to these plates. Any suggestions would be greatly appreciated. Thank you, Teal Renals

I don't think you need to worry about damaging the "plating" on stainless steel devices. Electropolishing and passivating do not leave a coating, rather they can be considered to be cleaning and/or metal removal processes. By the way, if the parts have been electropolished they probably do not even need the passivating.
