Dishwasher (just go ash)

Wood Ash (calcium carbonate)

As the world is going towards the traditional way of living life, the products sold in market are also attracting the customers in the name of organic products. 

As the use of fire-wood cooking is long gone, the availability and use of the wood ash is rarely seen including the rural regions. In the village the people used to cook their daily meal in the fire wood and pots. The ash leftover were used to wash the dishes.

The chemical composition of wood ash is calcium carbonate. All your dishwashers used on your day to day life contains calcium carbonate as the main ingredient for washing dish. Greasy stains such as oil, butter, over burnt food stains, etc. are all surface agents which require surfactants to act on it. As wood ash (natural calcium carbonate) are chemically having water-soluble tail and oil-soluble head.

From the above picture we can find that the surfactants contact with the dirt on the surface and the tail part gets attracted together and form pellet. In this manner the ash acts as a cleanser (dish washer, oil stain remover, oil absorbents, etc.). 

Many research is done on micro and Nano particle of calcium carbonate. The study also showed that in a lesser amount of surfactant region, the calcium carbonate surface will become lesser attractive to water and as the amount of surfactant is more, the attraction of like regions are reduced. This is because the single layer of surfactant molecules which is formed on the surface. When the amount of surfactant is increased the monolayer saturated with surfactant molecules that becomes from lesser water attractive molecule to more water attractive molecule by converting single layer surfactant to 2-layer of surfactant that lets the dirt to get separated from the vessels surface.

The above scientific explanation helps in understanding how ash removes stains from the surface. 

Apart from wood ash the combination with sand, tamarind, rock salt, etc. can be used to remove tough stains. So forget doing research on which soap to shop for removal of tough stains.

All you have to do is just get some wood ash and scrubber to see the magic done on your vessels that shine every day.
