Did you know that the way dishwashing liquid works is very clever? The solution contains molecules that have two opposing sides, one side is hydrophilic – means it loves water, and the other side is hydrophobic – which means it does everything it can to stay away from the water.
The hydrophobic sides of the molecules clings to the grease of the dirty dishes while the hydrophilic sides try their best to get into the water. Fortunately, the hydrophilic sides are a bit stronger and the molecules are drawn into the water with the grease attached.
