Cleaning RK05 packs (Was: LGP-30 Memory Drum Update)

[CuriousMarc]

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.

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.
