I would say, hot tap water and don't handle the disc too aggressively because you might well warp
it. Boiling water, no, at least not with a disc you care about. Maybe boiling water isn't so hot it
would warp or melt the plastic, maybe it is. I wouldn't want to find out it is by boiling a disc I
cared about!
In thinking about this thread, if I were you I'd try:
1. hot tap water and gentle pressure on the disc surface, supporting the disc on a flat surface if
possible
and if that doesn't work ...
2. isopropynol on something akin to a pelon wipe, appyling as gentle pressure as will remove the goo
and if that doesn't work ...
3. Naptha, same technique as the isopropynol.
Let us know what works, and if isoprop or naptha cloud up the plastic (I don't think they will, but
I don't know this for a fact). It would be good to have some actual experience-based knowledge!

How hot are we talking about, hot tap water, tap water too hot to touch, or water heated on a stove?
Wouldn't that damage the disc?
