A squirt of stain remover, applied to clothing before washing, often removes small, light grease stains from cotton and cotton-polyester blend fabrics, but tough grease stains require extra steps. Perform the stain treatment in stages, and check between each stage to see if the stain is still there. If the stain is gone after any of the individual stages, go on to the wash cycle.
Fold a paper towel until it is at least four layers thick and place it on a firm surface, under the grease-stained area of the cotton or cotton-poly blend fabric.
Dip the cotton ball or swab into all-purpose citrus cleaner, and cover the stain with the cleaner. Use a second paper towel to wipe inward around the edge of the stain, pushing down firmly the whole time. This pushes the stain inward while pushing excess grease down into the folded paper towel underneath.
Fold another paper towel to put under the stain as soon as you have worked all the way around the stain's edge. Put a few more drops of citrus cleaner on the stain, and continue to wipe the stain from the outer edge to the centre.
Check to see if the stain is still visible. If it still shows, allow the area to air-dry, then dust the stain with cornstarch. Place a folded paper towel under the stain and another one above it, and press down on the powdered stain. Let it rest for a half hour, then dust off the cornstarch with a soft brush.
Inspect the stained area. If it is gone, launder the fabric as you normally would. If the stain still shows but is very light, pour out a capful of liquid washing powder. Cover the spot with detergent and pour the rest into a bucket or washbasin. Gently rub the liquid detergent into the fibres of the fabric. Fill the bucket, or washbasin, with water. Submerge the soiled garment in the soapy water and let it soak overnight.
