Melted computer feet

[Zane Healy]

Is there any recommended method for cleaning up melted “rubber” feet on a plastic case?

I’m trying to determine if I can revive the VAXstation 4000/90 I received from a list member, back around 1998 (it’s never worked).  When I pulled it out, I discovered that its feet have melted, and I’m assuming probably made a mess on the disk enclosure for my VAXstation 3100 that it was on top of.
