You can try to cotton swab + acetone through the crevices but it takes a lot of effort and you might permanently damage the plastic as acetone also evaporates tiny bit of the plastic.
Remember this is Hasbro. The figure they show as prototype is not necessarily the mass produced product. Like pic related was advertised with metallic red. In this case, we might get lucky that Hasbro is so cheap that they cut corners on the washes so it doesn't look as horrible.
