Paint Swatch Cabinet Repainted (Did I Make The Right Decision?)

I didn’t need to try this with the cupboard pulled out as a result of, as you’ll be able to see, though I taped across the trim final time, I nonetheless managed to get black paint on the ground and wall.

I’m hoping I can get that up with a Magic Eraser earlier than pushing the cupboard again into place and placing a second coat of white paint on that backside trim. If it gained’t give you a Magic Eraser, I’ll have to do some touchups on the ground paint earlier than shifting the cupboard again into place.
