Its pretty brutal actually, just on a very small scale. Soap molecules have one end that likes to bond with water and one end they really doesn’t and tends to bond with lipids (fats, oils). Thats why soap works to wash oily substances off. But at the same time it means that when you have soap and water in a mixture with a virus it bonds on one end to water while the other is avoiding water. Little groups of these form and permeate the mixture, while the edges are avoiding water. What do they find instead? The lipid envelopes of a lot of viruses and bacteria. The hydrophobic end attaches to those envelopes and the virus or bacteria is literally ripped apart.
