Can't help with the hosting but I've always favoured Isopropyl Alcohol as a cleaning agent. It's sold by many companies including perfect data (from whom I purchased my bottle). :-) It's the same stuff that a lot of floppy drive cleaning disks use, also sold as Hi-Fi cleaning fluid etc.
Your local pharmacist may be able to sell you some too, but they'll probably ask you what you need it for.
