Oil-based soaps can be surprisingly effective at stain removal, especially for difficult stains such as grass and blood. They should be used immediately after the stain is produced for the most effective cleaning. However, oil-based soaps can also be used for old, set-in and stubborn stains. The procedure to use them is quite simple.
Things You'll Need
Solid bar of oil soap
Container of liquid oil soap
Scrubbing brush or clean towel
Place the freshly-stained garment in the sink. Begin running warm water.

Rub the solid bar of oil soap on the stained area of the garment under the running water. Or, pour a small amount--a few drops--on the stain if you prefer to use the liquid oil soap.
Scrub the stained area vigorously with the brush or towel until the stain begins to fade.
Rinse the stained area thoroughly.
Repeat Steps 1--4 if the stain is not satisfactorily removed upon the first try.
Wash the garment according to manufacturer directions immediately after performing the above steps.
Murphy Oil Soap is a good brand of liquid oil soap that can be used for stain removal. If the stain is old or very difficult, try applying the liquid oil soap and allow the garment to set for up to thirty minutes before washing it according to the above directions. Although it shouldn't harm fabrics, it's best to test the soap on a small area of the fabric before applying it fully. Simply place a dot of the liquid oil soap on the fabric and observe any reaction. If it appears safe, then proceed.
Oil soap may not be effective against grease or oil stains. Use dish soap for these stains instead.
