I'm about to go into a meeting and just realized I have lipstick on my shirt.
Lipstick on teeth: no problem (provided you notice it before anyone else does). Lipstick on clothing, however, can be a bit trickier. While foundation, powder and liquid blusher will respond to liquid soap dabbed on with a washcloth or sponge, lipstick and mascara require a cleaner that can attack oil-based stains. Kerr suggests keeping a secret stash of a solvent, such as Shout, Lestoil or even Pine-Sol, around; though your garment will probably require a full washing once you get home, a light application of the solvent will act as a quick-fix spot treatment to remove, or at least mute, the color.
