Start by rinsing the stain with cold water immediately. This helps prevent the turmeric from setting.
Make a paste with baking soda and water. Apply it to the stain, let it sit for about 30 minutes, then rinse with cold water.
Mix equal parts white vinegar and dish soap. Apply to the stain, let it sit for 15-20 minutes, and then rinse with cold water.
Apply lemon juice directly to the stain and let it sit in the sun for a while. The acidity helps lift the stain.
For white fabrics, apply a small amount of hydrogen peroxide directly to the stain. Let it sit for about 10 minutes, then rinse.
If the above methods don’t work, consider using a commercial stain remover. Follow the instructions on the label.
After treating the stain, wash the fabric as usual, but avoid using hot water, which can set the stain.
