Sprinkle cornstarch over the lip balm stain to absorb the oils. Leave the cornstarch on the carpet for 20 minutes before vacuuming it.
Pour dry-cleaning solvent onto a clean cloth until it's damp. Sponge the carpet with the dry-cleaning solvent to remove any color from the ChapStick.
Place 2 cups of warm water in a bucket. Add 1 tablespoon of dishwashing detergent and 1 tablespoon of white vinegar. Stir the ingredients until mixed well.
Moisten a clean cloth with the dishwashing detergent and vinegar solution. Blot the remaining ChapStick lip balm stain until it's removed.
Rinse your carpet by sponging it with a damp cloth. Absorb excess moisture in the carpet by pressing a dry cloth into the fibers. Allow the carpeting to air-dry completely. Fluff the carpet fibers with your fingers.
