<p class=MsoNormal><span style='color:black'>Keith –<o:p></o:p></span></p>
<p class=MsoNormal><span style='color:black'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='color:black'>First, it is very worthwhile to
use a cleanroom laundry service rather than trying to clean the garments
yourself. The cost of setup and maintenance of the equipment makes it
worthwhile only if you are laundering massive quantities of garments.
Without the right equipment and filtration on the dryers you will introduce
large quantities of particles – mostly organics – into your
cleanroom.<o:p></o:p></span></p>
<p class=MsoNormal><span style='color:black'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='color:black'>That said, it is really easy to
get “scalped” by cleanroom laundry suppliers. Some of them
are straightforward and honest, others are highly dishonest. The
dishonest ones will set a low per-garment price and make up the difference (and
more) in lost-garment charges, extra fees, etc. Be very careful how you
word your contract and what happens with “missing” garments.
If you rent garments, consider garment lifetime and the end-of-cycle value of
the garment. I had one company attempt to sell me a contract where the
garments maintained their value forever and I had to pay the full garment price
to end the lease – what I called “rent to never own.”
Realistically, a garment depreciates its full value over three years.<o:p></o:p></span></p>
<p class=MsoNormal><span style='color:black'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='color:black'>I have always found it most
cost-effective to purchase the garments from the garment manufacturer and
contract with the cleanroom laundry for cleaning only – called
“customer-owned goods (COG) in laundry jargon. If you can’t
afford the capital outlay, you can rent the garments but you need to be very
careful about the wording of the contract, as mentioned above.<o:p></o:p></span></p>
<p class=MsoNormal><span style='color:black'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='color:black'>A good laundry will supply you
with particle data on their cleanroom – the folding/packaging area is
critical – and more importantly particle count data on garments after
drying. The Helmke Drum test is the industry standard and gives good,
repeatable results. I also recommend a periodic (annual or
every-other-year) audit of their facility. They should be able to show
you good SPC data regarding their cleanliness, both of laundered goods and the
room. Also look at their sorting methods and the way they eliminate
cross-contamination between facilities.<o:p></o:p></span></p>
<p class=MsoNormal><span style='color:black'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='color:black'>I sound like I’m beating a
dead horse, but inventory control is the key to dealing with a laundry.
Make sure that you know how many garments you are shipping out and
receiving until you have established a trust with the laundry, then audit the
shipments periodically (I recommend monthly).<o:p></o:p></span></p>
<p class=MsoNormal><span style='color:black'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='color:black'>I’ve worked with a number of
major laundries over my years in industry, and chose Alsco Cleanroom Services
(formerly American Cleanroom Garments (ACG) on setting up the facility at
Purdue. They have served us well, and we recently renewed their contract.<o:p></o:p></span></p>
<p class=MsoNormal><span style='color:black'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='color:black'>I also use them to launder my
cleanroom-cleaning materials, such as cleanroom mops. That is very
cost-effective.<o:p></o:p></span></p>
<p class=MsoNormal><span style='color:black'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='color:black'>Please let me know if you need
further information and/or details. I’ve been through the ringer
with cleanroom laundries (pun intended) and ended up saving tens of thousands
of dollars in a production facility by taking the loopholes out of the contract
and ending up with a program that was fair to both companies, mine and the
laundry.<o:p></o:p></span></p>
