Dry cleaning is ideal for expensive clothes or those that require a lot of effort to be washed. It can work well with a machine and there are certain chemicals that are used to clean the clothes. The solvents that are used to remove any kind of stain or dusts are either used prior to the wash or during the wash, depending on the fabric used. Dry cleaning does not involve the use of water since many fabrics do not respond well with water and tart losing their color. Tetrachloroethylene, more commonly known as perchloroethylene is the chemical used in the process.
The chemicals ensure that there is minimum wear and tear while the washing is going on and there is absolutely no fading of color or bleeding from the clothes. Infact more often than not, dry washing gives a boost to the life of the clothes making them fresh and less vulnerable to wear and tear.
