Here is the exact reference for the clean room wipes: Berkshire DURX 670 Item #: DR670.0404.10 4"x4" (10cm x10 cm) Non-woven Polyester/Cellulose
And isopropyl alcohol we use is 99.9%, not just 99 as I said. Marc -----Original Message----- We use 6"x6" clean room rated wipes (I think they were either Berkshires or Kimwipes) from Grainger and 99% isopropyl alcohol from Fry's. Won't scratch, free of microscopic dust and lint, and 99% alcohol will leave no drying marks (it's typically the last rinse in IC manufacturing). May cost you a bit. Wipe your work area before and use clean room gloves. Marc > On Jan 5, 2017, at 6:40 AM, Al Kossow <[email protected]> wrote: > > isopropyl alcohol works.
