Alkaline Cleaner for Metalic Medical Devices

[Jimmy2]

Hi,

Can anyone recomend a good alkaline cleaner that will remove polish and other tough residues in an ultrasonic bath from titanium, stainles or cobalt chrome. Or any good cleaner for these residues?

Cheers
Jim.

When I ran a test lab in the UK (eons ago) we used to use Decon 90 for cleaning stainless steel, glass etc items in an ultrasonic bath. FYI nowadays because we require ‘oxygen clean’ metal components for our medical devices, we use a solvent system rather than such an alkaline aqueous product, in our case Vapour-Kleen (see previous thread http://elsmar.com/Forums/showthread.php?t=44492).

Don’t know if this helps.

Hi Jimmy2,
based on my experience (validation of cleaning processes for endoprothesis) the choice of the right cleaner highly depends on the residues you use. We found out that testing is the only way to find the right one, because there are so many different residues and so many cleaners. We use ELMA SONIC X-TRA, but just had the case that one technican changed the tapping fluid and our testing showed that the cleaning process was not sufficient. I would also recommend to change times and frequency of the cleaning process during testing.

Cannot disagree with what phloQS has indicated. In this respect you may wish to look in the annexes of ISO 15001 wrt to cleaning methods and validation (though it is specific to respiratory type MDs).
