The way that washing liquid works is actually very simple. The solution contains molecules with two opposing sides - one side is hydrophilic (meaning it loves water) and one end is hydrophobic (meaning that it does everything it can to stay away from water). The hydrophobic ends of the moleculesto clink the grease on your dirty dishes, while the hydrophilic ends try their best to reach the water. Fortunately, hydrophilic ends are a little stronger; and the molecules are drawn into the water, with the grease attached.
