Scoop as much paint off the carpet as possible with a plastic craft knife or the back of a butter knife.
Apply non-acetone nail polish remover to a cloth or towel. Begin dabbing from the outside of the stain toward the center.
Pour enough glycerin to cover the stain over the stained area. Allow the glycerin to work on the stain for at least an hour.
Mix equal parts liquid soap and water. Use a plastic scrubbing sponge to work the soapy mixture into the stain.
Rinse the area thoroughly with club soda once the paint stain is fully removed. The club soda helps loosen any remaining paint and soap residue from carpet fibers.
Blot the area well until the carpet is completely dry.
