Grease stains won't ruin your clothes if you use this method right away. You don't even need to soak or wash your clothes. One ingredient and the problem will disappear as if it never happened.
Details
To get rid of grease stains on clothes without using chemicals or washing, sprinkle baking soda on the fresh stain. Then, place paper or a napkin on top, then a piece of cloth, and run a hot iron over it.
After that, just shake off the baking soda. If any baking soda remains, scrape it off. An old toothbrush will help a lot.
Regular salt will also effectively remove grease stains. It should be rubbed onto the grease stain, but immediately after the “mess” has occurred. Salt is a more convenient method, for example, in nature, when there is no iron in your pocket and no box of soda at a picnic.
