im sorry to hear about the mishap. you can carefully have it sprayed with water and dishwasher mix (more dilute than usual) and it should be enough. however, in my opinion it only is enough until you are 100% sure that you have washed all spilt on areas.

if bare metal is exposed then you might have to respray with paint just enough to cover the exposed and "almost-exposed" parts evenly. Rust starts from oxygen concentration (or non-concentration, thereof) of certain areas relative to another.

(Of course there are other rust initators out there, but im just talking about exposure of a certain area to oxygen as compared to another area.)
