Set the cycle you'd usually use for this type of clothing and wash with the usual detergent. Hopefully the washing machine can get rid of the excess paint that you weren’t able to remove with the scrubbing and the alcohol. Hopefully the stain will have been lifted out by both the alcohol and the wash. If you aren’t satisfied you can repeat the process over again, but it might be too late.

TL;DR in Indonesian:
Masukan pakaian ke dalam mesin cuci. Keringkan seperti biasa.
