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.

isopropyl alcohol works. TFE is better, if you have some stashed.
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.

We clean our RK05 disks in a very robust way:
with cheap burning spirit
and paper towels. ... We rubbed away thick black traces from occasional
head crashes and we never removed the oxide coating with this torture.
I am about to get a large batch of RK05 packs, so I am interested in the
details of this.
First, what is 'burning spirit'? (I assume this is a straight translation
into English of some German term, but not knowing German... :-) After poking
around with Google for a while (hampered no little by the fact that it's the
name of a band, and also a term in World of Warcraft :-), it seems like it
might be acetone?
