How to remove ink marks on a (white) 7-tales Sweetheart?

[Nella]

I have a beautiful white Sweetheart with awful blue ink marks on her head . She has great hair, nice symbols etc. But the marks really ruin her. 

What can I do? Her head must keep the same color as her body....

Have you tried using acetone, yet?

[Nella]

Haven't tried anything yet. Too afraid to ruin the white body. The ink really is in the plastic, not on top of it.

You could try sunfading her. I have had great results sunfading inkmarks

I think I'll try sunfading, never done that before. Any tips? Is it best to bring her outside to have the maximum result? And will the tin foil leave marks on her body?

[The_Loner]

It's not necessary to bring her outside, a sunny windowsill works just fine. I have never had the tinfoil leave any marks, but be sure to check on her every day. Good luck

sunfading the best for ink.

Acetone does not remove ink stains.  Sunfading is the only way to go as long as the pony isn't prone to burning.
