Use some aloe vera, dish soap, or shampoo as a pre-wash stain remover. Blot any excess oil using a clean cloth or a paper towel. Then, squirt some aloe vera, dish soap, or shampoo onto the stain. Use an old toothbrush or a manicure brush to rub the stain into the fabric
Just mix Dawn dish washing soap and some baking soda into a paste and apply to the area. Scrub well and then launder as usual. If the stain is tomato based, you may need to apply a bit of Oxi-clean.
Hi Angela, I had one that I had washed and dried. I put dawn ultra straight on the stain and scrubbed it together. I let it set for about 15 minutes and then washed and it came out.
If it is a tough stain, use the side of a spoon to work the Dawn into the fabric. Just be sure not to scrub hard enough to break the fibers.
This is a great post on removing grease from clothes even if you've already washed them.
