Method 1: For newly stained tomato juice stains, you can apply salt on the stain (let the juice adsorb on it) - moisten it with water - and wash it with soap.

Method 2: If it is already dry, rub it with white vinegar - let it sit for 5 minutes - and then rinse it with water.

Method 3: Dissolve baking soda with water - scrub.

The last trick is also a strange trick: colored fabrics are washed with concentrated salt water → water wash → 10% ammonia water → detergent wash; white fabrics can be washed in bleach solution (3-5 sodium hypochlorite solution) Soak for 1 to 2 hours and then rinse with clean water.

In addition, you can also use explosive salt to rinse, and the effect is also good.
