I wouldn't use acetone or MEK. It looks like mildew, if you're not careful with solvents, what happens is the solvent melts the surface of the material & mixes in the muck from the mildew & bonds it to the surface. The solvent evaporates, the surface sets & hey presto, a nice mildew paint job. I'd attack it with strong non-solvent cleaners like TFR or bleach.
