Process of Dry Cleaning

Dry cleaning is method of cleaning fabrics with chemical solvents instead of soap and water. Petrol is the most important of them. Benzene is also used in dry cleaning. Some safer synthetic chemicals such as polychloroalkanes and alkanes have also been developed. The most common dry cleaning chemicals are carbon tetrachloride and trichloro ethylene. In a dry cleaning establishment, clothes are usually treated first for stains. Then they are placed in the dry-cleaning machine with the cleaning fluid or solvent and tumbled slowly for up to half an hour.

After a rinse in clean fluid, the cloths are spun around rapidly to extract the liquid and are finally fluffed in hot air. Any stains remaining are removed by hand and clothes and then steam pressed. Dry cleaning has several advantages over ordinary soap cleaning. The process is most useful for delicate or expensive silken and woollen fabrics because it does not have any undersirable effect on them. For instance the colours do not fade as they might in water.
