As a follow up to my original question, I will say that we have a stand
alone washing machine here at the LNF that we'll use for cleaning heavily
soiled items (lab smocks, and a clean room suit or two) before we send them
out to our laundry processor. Our machine is set up to use ambient
temperature DI water (and CR-2 cleaner), but the unit is just an
off-the-shelf machine that we got from one of the big box stores. It has a
stainless steel drum, and our thought with the DI water is that as soon as
the water hits the equipment, it's way less than DI, but still way cleaner
than city water. It allows us to pretreat garments that might have gotten
excessively soiled as part of a maintenance project. Our experience with
Cintas is that they're not set up to do a Tide commercial for clean
clothes, but we still want the additional support they provide in regard to
a final clean, and the packaging.
This has been a good conversational thread. I don't know if we'll change
our practices, or vendor, but it has been a great discussion. Thanks to
all who chimed in with their experiences, and input.
This is truly a handy forum to have.
