Why Turmeric Stains Everything, According To Science - Tasting Table
Briefly

Curcumin, the active component in turmeric, gives the spice its vibrant yellow color and is responsible for its ability to stain easily and stubbornly. The curcumin molecules bind to fibers, leading to immediate discoloration of fabrics and surfaces. Additionally, turmeric particles possess an oily quality and are not water-soluble, making them resistant to typical stain removers. To remove turmeric stains, apply white vinegar on fabric and blot. For countertops, using baking soda in combination with vinegar can effectively address the stains, though caution is advised on wooden surfaces.
