My friend was told that her car might have a cracked head. So when she changed her oil she added some of this

Bar's Leaks Block Seal Liquid Copper Coolant Leak Fix 

In, however that stuff was suppose to go in the radiator. Lol. Anyway what's done is done so my question is how does she get that out?
