Here’s how you can remove grease stains safely at home. You’ll need a double sink or bucket, a jug of white vinegar, a cleaner like Woolite, and half a bucket of ice cubes. First, submerge the item in an ice water bath. The thermal shock of the cold causes the fabric to contract, pushing debris to the surface. Let the item sit in the polar bear bath water for 20 minutes. Next, soak the item in enough white vinegar to fully cover and let sit for a few hours, even overnight. The vinegar separates the stain from the fabric, ready for step three. In cold water, gently sudse the item with Woolite. Now rinse completely and air dry. Even if there’s still evidence of the grease mark, since you did not set the stain with heat, we may be able to work a dry cleaning miracle.
