How to remove expanding foam from bifolds

longwalks1

We have a few marks on our bifold door frames (painted white aluminium) from expanding foam, a kind of dark orange residue

What’s best to remove it please, without damaging the white paint?

Grenage

I'd start with a free Stanley blade, keeping the angle as shallow as possible.

try nail varnish remover but remember to wash off afterwards before it bites into the painted finish

Gloomendoom

I've use foam eater for similar issues...
