It's metal so I dropped into some Pine sol overnight.
When I scrubbed it, it was gummy; sticking to the brush and my fingers.
So I dropped it in again and let it soak for over a week.
It had to be clean now..right? Nope.
Just as gummy. I had no idea how many layers or what kind of paint
I used Goop hand cleaner to clean my fingers & the brushes, so I fuigured..why not?
I so I soaked the model in it. [the Goop is old and liquid, not a cream.]
After several days I checked it. It washed right off. Non-toxic. Safe on hands and actually cleans them.
I'll try it on a plastic model next.
