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.

If you can find them anywhere, Texwipe made a plastic wand that looks
like a tongue depressor with a slit down the middle and a lint free
sleeve called the Texsleeve (tx300 sleeve, tx800 wand) that you would
use to clean heads
Minor head crashes leave a tar-like residue that you need to remove. A
pack inspector is a handy thing to have (spinle with microscope and
illuminator on the rack and pinion) to look for surface damage.
