Any ideas how to get door paint off wall paint?

[kissmelittleass]

Was painting door trims with white undercoat paint yesterday and today I noticed in two places on sitting room wall there are white brush marks and they are showing up like shiny grease stains, the wall is painted in Ivory white and only painted a year ago 😫
Tried dabbing with a damp cloth but no good and obviously it's dried in as happened yesterday!!
Any idea? Or do I have to put up with it? Very upset with myself!!

I would use very fine sandpaper then repaint. It is easy to mark the plaster doing this as you only want to remove the paint. You also need to be very sure of the colour and hope it hasn't faded on the wall.

You could also try just painting over it. May show through or have a very slightly raised profile.
