How to Get Rid of the 12 Most Stubborn Stains
Stretch the fabric over a bowl and carefully pour boiling water through the stain from about a foot above. If the coffee had milk in it, follow with an oil solvent, like Carbona Stain Wizard Pre-Wash ($4.50, soap.com). If it contained sugar, follow with a pretreatment product, like Shout Laundry Stain Remover ($4.50, cvs.com), and let sit for 30 minutes before washing.
Apply Shout, then apply white vinegar with an eyedropper or a clean toothbrush to lighten the stain.
Saturate the stain with white vinegar, then apply a dish-soap solution. (For the formula, see Chocolate.)
Flush with cool water. Apply a prewash stain-removal product (like Shout), then soak in a sink filled with cool water and a few drops of detergent.
Run cold water over the stain, then spray with a dish-soap solution (see Chocolate) and pretreat by dabbing with detergent.
Treat with Shout and let sit for 15 minutes. Use a clean toothbrush to rub in the solution.
When the stain is dry, gently scrape off the excess with a plastic knife. Dab on a bit of water and some gentle detergent (like Woolite). Rub to form suds, then rinse. To lighten the remaining stain, apply a solution of 1 part water and 1 part white vinegar.
Apply Amodex Ink and Stain Remover ($16, wayfair.com) to the area. Rub in with a clean, stiff-bristled toothbrush until the ink is almost gone.
To stop the stain from spreading, create a "dam" around it with petroleum jelly. Then apply isopropyl alcohol with an eyedropper or a clean toothbrush. Dab with a cotton ball and mineral spirits to remove any residue. (Open a window for ventilation.) Let dry. Rinse with a dish-soap solution (see Chocolate).
