Getting acrylic paint off a t shirt - is it possible?

[carriemumsnet]

Ok so dd is on an art course at school all week. Goes for a sleepover and packs her bag herself and manages to pack without me knowing a T shirt that she borrowed from a friend (on condition that she would take very good care of it cos it's a favourite.) Comes home with said T shirt covered in acrylic paint. Am v pissed off with art teacher for not making them cover up and/or using paint with 8 year olds that doesn't wash off easily but anger isn't going to get me anywhere ... Anyway thought if anyone would know what to do to rectify you would. Anyone??
PS have thought of trying to buy a new T shirt, but it's last year's range.. that'll be next step - trying to buy a second hand one!!

Get the second one or something extremely nice to replace it, the only way you can remove acrylic paint, is by doing it immediatly, although it doesn't work properly in most cases.
