ELI5: what makes bleach such a powerful pigment remover?
gpt
Bleach destroys molecular bonds. Pigments (in order to function like a pigment) tend to be quite precise and complex combinations of atoms. Compare it to turning a car into nuts and bolts, except at the atomic level. This is also why bleach works on *most* stains, but not stuff like rust stains (as this is simply a combination of 2 or 5 iron/oxygen molecules depending on the state of iron)
