As we all know, cloth sofa is not resistant to dirt, and it will leave stubborn stains if you are not careful. At this time, you can use a soft brush dipped in a little alcohol to wipe it once, and then use a hair dryer to dry it. If the stain is fruit juice, it is recommended to mix it with 1 teaspoon of soda powder+water, and wipe it with a cloth. The stain can be easily removed. If you also have cloth sofa, or plush toys, you might as well try it.
