How to Remove Grease Stains
WHAT TO KNOW
For new stains, you'll be able to use the quick technique described in the video below, which involves cornstarch -- something you might already have in your pantry. Most older stains, however, will generally be better tackled with a solution of water and Orvus, a water-soluble detergent. You can pick it up at tack stores, saddleries, or online. It's also a good idea to have some super-absorbent cheesecloth on hand.
And, as with all stains, you'll want to act relatively quickly.
WHAT TO DO
1. Treat area with a dry solvent (such as mineral spirits or acetone) in a well-ventilated room.
2. Using an eyedropper, rinse with isopropyl alcohol; dry well.
3. Spray diluted dishwashing-soap or Orvus solution on any remaining residue, and soak the item in an enzyme detergent (Biz, Era Plus, Wisk, Shout) before washing.
