Brake fluid got on painted firewall, what to clean with?

Brake fluid will go right through fresh paint. You'll probably need to sand and repaint the clearcoat atleast.
My car was painted with single stage in 92. The master cylinder went out during the drive home. I still have the previous owners palm print on top of the left fender today.
I'd be much happier if the damage was on the firewall instead. Good luck
