[CCTALK] Keycap cleaning strategy

I've found that _yellowing_ is a worse problem than cleaning. (EXTREME WARNING: Use the following techniques only on DOUBLE-SHOT molded keytops. If you don't know what this is, you shouldn't be doing this.) I simply take a picture of the keyboard, remove the keycaps, soak 'em in Formula 409, and replace them if they are just dirty. If they are yellowed, here's how I dealt with a severely yellowed Hazeltine 1000 keyboard (the keys were actually BROWN, not ivory): 1. Took pic and removed keycaps. 2. Used 400 grit wet or dry sandpaper on keycap sides, placing sandpaper on flat suface. 3. I couldn't use the sandpaper on the tops because of the indentation, so I got a tiny Dremel wire brush and removed the top layer (very carefully, without gouging or misshaping the keytop). 4. Got a buffer wheel for my drill and some automotive rubbing compound and buffed the keys back to like-new condition! 5. Replaced keys according to picture. --- John Allain <allain(a)panix.com> wrote: __________________________________________________ Do You Yahoo!? LAUNCH - Your Yahoo!
