उत्तर

There is no alternative to water for cleaning purposes, because it dissolves everything that is added to it. The reason why it is called the universal solvent. The water dissolves all the dirt present in our clothes, the reason why we soak our clothes in detergent and water prior to washing. Also, water has a neutral pH, which means it does not harm the object which has to be cleaned and also does not affect the skin.
