Caustic soda is so powerful that it can eat away paint on the surface of metal. Generally, Caustic soda is used to clean the old paint on metals of car and other vehicles while repainting.

- Soaps remove the natural oils on skin
Our skin produces natural oils from oil glands on it. Those natural oils are very helpful in preventing skin damages. But with the regular usage of skin soaps, those useful oils are cleaned away. This makes our skin turn dry and little bit itchy too. So, this is also a big disadvantage for your skin.

Soaps we use daily comes with high pH level. This washes away the useful acid layer on skin. Even scientists say that this layer helps skin in defence against micro organisms. By using skin soaps daily, we lose this useful acid shawl and suffer from many skin diseases.
