How Do I Remove "Smooze?"

[JanuaryJoy]

MLP Preservation Project has info on removing ingrained dirt or "smooze," but it's literally one paragraph. I've never tackled this before, so I'd like better instructions or advise from somebody experienced. My afflicted ponies are Moondancer, who only has dirty hooves, and Skyflier, who's grubby all over the legs.

To clarify, a magic eraser sponge did nothing for either pony. They both have delicate glitter symbols, so I don't know if they're safe to boil...? I just feel uncertain all around. I'm worried I'll accidentally damage them somehow, especially since I may need to scrape at the dirt using a sharp object. Thanks in advance for any advise!

You can simply dip their legs into the boiling water, you do not need to submerge the entire pony unless the entire pony is affected.
There's a few other threads that discuss. Here's one and here's another.
I've not been successful myself really, but I've only tried a handful of times. If someone has any better methods, hopefully they'll throw it out here.

Unfortunately, doing the boiling water plus scraping method is the most effective. Though I've heard people have had success using a blackhead remover tool as well. You still need to boil to loosen up the plastic pores but TRTL is right, you'd only have to submerge the legs
