Paint on plastic extractor hood

[JamesAsus]

Brand new extractor hood, black, got some white 'easycare' wipeable dulux paint on it, got the thick stuff off but there is faint white smudges on it i cant get off, been on a week now.

Any ideas to remove white 'easycare' paint off a black plastic extractor hood? Cant pick it off due to how thin it is.

Meths with remove water based paint but I'd try steam cleaner first.
Always do a test spot first

This be any good?

Yeah. That will do.
Do test though as you don't want it to effect the original coating
