Ancient adhesive on plastic key tops

[Alan R. Barnard]

First, apply heat (gently) to warm the tape. It will likely come right off.
The residue should come off with a little oil rubbed in it ... even cooking
oil or WD40 ... then use a damp rag, maybe with a dab of detergent.

Bet it works. Let us know.
