Does ketchup actually work to clean dirt off whites?

It works because it is acidic. Same results with white viniger (cheaper) and shampoo. And you can was white/grey horses with this mix. The look amazing after.
I usually mix ketchup with my purple shampoo and it works brilliant.
Never tried ketchup but I know blue shampoo works on my boys white legs.
Not really. It might make a white tail whiter just
