There are 4 major ways of cleaning fabrics. Steam' - this is the most common method and is fully acceptable for synthetic fibres. These fibres are not 'moisture sensitive'. Moisture sensitive fabrics that have too much moisture will cause a negative effect on the structure of the fabric. The more moisture sensitive the fabric, the less moisture we can use and this determines which shampoo we use.
More moisture used usually produces better cleaning results.
This a more expensive method of cleaning as it takes even more time and the cleaning agent has a high cost as well. Solvents do not remove as much soil as water based methods will. The fourth method is a combination of the above methods. For example, we would use cotton shampoo and a mist steam rinse for most heavily soiled cotton fabrics. The mist performs the rinsing portion of the procedure of cleaning.
