Earlier today i sat unscrewing my pipe to remove the bowl; the ugly thing fell onto my lap smearing ungodly marijuana resin onto my shorts

:
I've given them several good washes & hand washes, its still there. I mean, i was going to throw them away but i only bought them a month or so ago.
Any suggestions on how to remove this vile shit? Acetone? Ethanol? Fire?
& Yeah, this is a self serving thread. I'm guilty.
