I’m not sure where to put this post as i just made an account to post this but i recently spilled nail polish on my original dark magic and i have not figured out a way to get it off i can post pictures if necessary.
Where is it on the yoyo - body, caps or rim? Nail polish remover contains acetone which will have an effect on the plastic body. Maybe better to just leave it if that’s the case. Acetone will soften the plastic body unless used sparingly. It will mar the surface in any event. If it’s on the rim it will be easier to remove. If it’s on the caps it will no doubt mar those too.
It is pretty much every where its not a big deal im fine with how it is now
