Sometimes sweatshirts end up with grease and oil stains on them--whether you're working on your car or cooking in the kitchen, it's inevitable. Getting grease and oil stains out of a sweatshirt isn't as hard as you may think. A little pre-treating and washing the clothing at the proper temperature goes a long way.
Things You'll Need
Pre-laundry stain remover spray or liquid
Blot off any excess grease or oil if the stain is fresh.
Pre-treat the sweatshirt with a pre-laundry stain remover that is specifically for grease and oil stains.
Let the pre-treatment sit on the sweatshirt for a few hours. The older the stain is, the longer you should let the sweatshirt sit.
Wash the sweatshirt as normal, in warm water. Warm water is key for removing grease stains.
Start the process a second time if the stain is still there after being washed. Do not put the sweatshirt in the dryer. Pre-treat it and leave it; then wash it again until the stain is gone. It may take several attempts.
