Re-cleaning Medical Device Vendor Parts
Q. Current procedure calls for an ultrasonic bath at 69C for 20 mins with Liquinox® and DI water. Then calls for another such DI bath at 69C with NO detergent for 20 mins. Then a 1 min DI water flushing. Is Liquinox appropriate? When I clean the parts, they have already been cleaned by vendor in the exact same manner, essentially I re-clean them. Is this overkill?

Ultrasonic Cleaning of Optical Devices
Q. Ultrasonic and forced DI water are not removing particles from the optical devices. We suspect that the particles are charged and that is playing a role in the difficulty of removing them. Rusting isn’t a problem but oxidation might be. Al, Ti are metals in the devices we use. The cleaning is followed by chemical etching so this can be an issue.
