You might love your glass of red wine, but not once you spill it on your clothes! Try soaking the stained area in water and then making a pouch in the cloth where the wine stain is. Next, pour cream of tartar into the pouched area. Tie the ends of the pouch and then let the garment soak. After soaking, dip it in and out of hot water and then launder as usual.
If the red wine stain is fresh, soak up the spill by immediately sprinkling it with baking soda. Next, as soon as possible, stretch the stained fabric over a large bowl or kettle, secure the fabric and pour boiling water through the stain.
Similarly, you can use salt for this purpose by sprinkling it on a spill immediately and letting it soak up the stain. Afterward, soak the stained area in cold water and then launder the garment as usual.
