Spilled grape juice on a T-shirt at a party? Don’t worry – science can help!

warm baking soda solution.
It’s always a shame when grape juice stains new clothes. But never fear – science is here to save the day! Just soak your T-shirt in a warm baking soda solution, then rinse it with water – the stain will disappear!
The anthocyanins contained in grapes readily bind to cotton fibers via very weak chemical bonds – so-called hydrogen bonds. These bonds break down in the alkaline medium created by the baking soda solution.
