My dad and I are having a debate about the importance of using washing up liquid and I need your help!!
He proffers that water in itself is clean, so why can we not just use water to clean our plates etc.
He also gave an example of how we would likely feel cleaner after “trudging through the jungle”, if we had a wash in a big jungle waterfall without soap.
I showed him that his glasses come out looking cleaner (no water marks) when he washes them with washing up liquid to prove my point that it is important to use it.
But can anyone tell me the actual science behind why we should use it? Or is my dad right? 😂

Fats and oils. They don’t dissolve in water, so if you don’t use soap, a lot of that oily residue is left behind.
Soap molecules are long and have one end that mixes with water and the opposite end that mixes with fat. It lets water wash off and carry away the fats and oils that water alone couldn’t.
