Microscopic damage to plastic parts?? Really? How did you prove that? Do
you have photos? What plastic?

Subject: [TN] US Cleaning in IPA

We're currently ultrasonically cleaning some plastic parts in DI water
and may be incurring some microscopic damage to the surface.

We've been directed to use IPA rather than DI water as a cleaning medium
to give a gentler clean to reduce damage.

Does this sound like a good plan and would there be any other fluids
that would be more suitable?

Regards,
