[labnetwork] Cleanroom Wipes

[Martin, Michael]

Hi everyone,
   Our stock of cleanroom wipes is finally coming to an end.  At some point we bought many cases of these and so we have not had to buy them for years.  We are using TechniCloth nonwoven wipers, 9"x9" 55% cellulose and 45% polyester part number TX609.  We have noticed in the last year or so that these seem to be leaving noticeable particulates which is particulary evident as we wipe off laptops and cell phones coming into the lab.
   So, what recommendations would you have for these?  Do you use different grades/types for litho, the cleanroom proper and the gowning room? Where do you purchase these?
    I see no expiration date on our wipes but do they expire?  Have you noticed old new stock that performs worse than brand new?


Thanks so much​,
