Beef steak is a protein stain and can be removed by soaking or rubbing the stain with cold water before washing. Never use hot water because it can actually cook the stain and drive it deeper into the fabric fibers. Use this method if the steak is raw or cooked with no added sauces or oils.
Some cooking methods leave a steak with fatty juices that need a stain-removal pretreatment to remove them. After treating, they also need the hottest water safe for the type of fabric to rinse them away. And, if you've chosen to top it with steak sauce, a bit more effort at stain removal is needed.
If the garment is dry clean only, point out and identify the stain to your professional cleaner. If you are using a home dry cleaning kit, be sure to treat the stain with the provided stain remover before putting the garment in the dryer bag.
