Ketchup is a mixture of many ingredients both ionic and covalent
Detergent is composed of chemicals that have ionic bonds. Ionic bonds are attracted to covalent bonds (sort of like the phrase "opposites attract"). Since ketchup and other materials that stain are made up of covalent-bonded elements, the ionic bonds in the detergent molecules cause the molecules in the detergent to try and bond with the ketchup molecules, separating them from the clothing.
