Awww, alphamale, sportin the good ole ibanez? Those things are damn skinnier than my Washubrn

....makes my bass feel like its a fattie or something
anyways...get any cloth that is "Microfiber"....but if ur really not sure, just go to a music store and get a decent cloth (it should look fuzzy...and well...it just looks like it would clean well

)
and, uhm well, to clean the pickups...u just have to dig down there and dust them out. I don't know if there's anything special that one could possibly do
For cleaning underneath my strings, and the fretboard, I use a separate cloth, and work it underneath the strings and use a back-and-forth motion to clean the underside of the strings, and the top of the fretboard.
as a digression, I highly suggest buying some "GHS Fast Fret"
You'll wonder how you got by without it
