Gearheads and Chefs alike end up smearing grease on their clothes. To capture this hydrophobic substance, you’ll need a surfactant like a dish soap. Apply a small dab to the area, wet it, gently rub it in, and wash it out.
For really tough grease stains, look for industrial soaps. They use the same action but have a stronger pull. However, for delicate garments that aren’t colorfast—that is, where the dye hasn’t fully permeated the fibers—industrial soap may strip dye as well as grease out of your clothing.
Toner and ink
Since the ink is the kind of solution that is supposed to be permanent, you need to resort to solvents for this type of stain. (This is why your parents run for the hairspray; it used to be loaded with alcohol, although you won’t find that solvent in most modern formulas.) To lift it out, you need to bust out a rag and some alcohol. Soak a sturdy cloth rag that you won’t mind ruining in the solvent; as the ink dissolves, it’ll transfer to the rag. After you’ve dabbed the stain a few times, try applying an oxidizer to take the color out of what’s left.
