4.+Tough+on+grease

To test the claim that the detergent was tough on grease we used different types of dirt and soaked in our three test detergents mixed at 5 drops per 200 ml of freshly boiled water and 10 drops of detergent per 200 ml of freshly boiled water.

The dirt types were
 * Nutella smeared knives (Protein and Fat)
 * Roasting grease-smeared knives (Fat)
 * Low fat yoghurt baked spoons (Protein)
