Minor paint touch-ups are occasionally needed, and while repainting entire areas can be costly, this cotton swab hack can repair marks on your wall in no time.
Lay down some protective floor coverings and clean the surface you intend to paint with a wet rag to remove dust or debris, then apply matching paint to your cotton swab.
Gently rub the cotton swab on the surface as if using a small paintbrush. This hack can save you time repainting the walls while avoiding wasting paint on small surfaces.
