* "Like dissolves like": This is a fundamental principle in chemistry. Polar substances (like water) dissolve other polar substances. Nonpolar substances (like oil) dissolve other nonpolar substances.
Since the oil stain is nonpolar, you'll need a nonpolar solvent to remove it. Here are some common options:
* Rubbing alcohol (isopropyl alcohol): While it's not completely nonpolar, it has enough nonpolar character to help dissolve some oils.
* Acetone: A strong solvent found in nail polish remover, acetone is quite effective at removing oil stains.
* Mineral spirits: This is a petroleum-based solvent often used for cleaning paint brushes and other oily messes.
* Dish soap: While it is primarily polar, dish soap contains surfactants that can help break up oil and grease, making it easier to remove.
Important tips:
* Test a hidden area first: Before applying any solvent to your shirt, try it on a hidden seam to make sure it doesn't damage the fabric.
* Blot, don't rub: Rubbing can spread the stain. Gently blot the stain with a clean cloth or paper towel.
* Rinse well: After using any solvent, make sure to rinse the area thoroughly with water to remove any residue.
