Suits and expensive coats are often taken to a dry-cleaning store to be dry-cleaned. But what exactly is dry cleaning?
I thought that since it is called "dry," it is supposed to be removed by blowing air like a hair dryer. I thought so, but when I looked it up, I found out that it is not the same thing. Dry cleaning mainly uses an oil-like substance called an organic solvent instead of water. What is different from normal laundry is that what is used is either water or organic solvent, and the clothes are washed and dried in a machine like a normal washing machine. Organic solvents are also volatile, so when they are dried, they basically do not remain on the clothes.
Organic solvents used to be made of strong-smelling oils or oils that could ignite quickly, but nowadays petroleum-based solvents are used, which ignite only at high pitch. So what are the advantages and disadvantages of dry cleaning?
Oil is insoluble in water, so when you want to remove oil stains, the petroleum-based solvents of dry cleaning may be better than washing in water. (Although with detergent, some stains can be removed by washing with water.) The biggest advantage, however, is that it does not easily lose its shape. For example, if the fabric is 100% wool or something like that, washing in water may cause it to expand and deform the clothes, but with organic solvents, this is not the case. This video is easy to understand.
The disadvantage is that sweat and other stains cannot be removed by dry cleaning because they are soluble in water.
So, if you only take your clothes to dry cleaners, sweat stains will accumulate and yellowing may occur. That is something to keep in mind. In dry cleaning, you have optional plans. Some of those plans seem to remove sweat stains as well. (Even without a plan, there may be dry cleaners that will remove sweat stains as well.) As mentioned above, dry cleaning is the process of removing sweat stains from clothes.
