– Why do we need to use washing up liquid to clean dishes? Why would water alone not suffice?

379 views

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? 😂

Some stuff in your plates like to bond with water and is taken away by the water flow. But a lot of stuff won’t bond with water and so we use soap to bond with them AND with water. You can then rincé them all away.
