Guess who put a heatsink down on a fabric-covered chair, forgetting that
the underside would be liberally buttered in this truly *evil* stuff.
What on earth will dissolve it without taking the chair with it?

Please help before she moves the cushion.... or I'm dead meat!

Have you tried working some washing up liquid into it with a
toothbrush then repeatedly rinsing with a sponge, dabbing with a dry
cloth and scrubbing some more?
