Tips for cleaning clothes
The secret of classification
Sort by color. Wash all white fabrics separately, soft and neutral colors together, bright and dark colors together. Note that clothes made of white and light artificial materials may be dyed by other fabrics. Ensure that lace and decorative patterns do not fade.
Sort by stain. Separate these particularly dirty clothes from those that are not too dirty, because cleaner clothes may get dirtier in the washing water. White clothes may gradually turn gray or yellow, and the color will become more and more gray.
Consider a special species.
Does not match. Every time the washing machine washes, small pieces and large pieces can be mixed together, so that clothes can move more freely and the washed clothes are cleaner.
Fabric type. Consider the materials, how they are woven. Loosely woven coats should be distinguished from fine materials and ordinary clothes, and should be gently graded when washing.
Clothes that fall off easily. Plush pullovers, woolen blouses, flannel clothes, new towels, etc. are easy to make other clothes fluff when washing, so these things should be washed separately-apart from corduroy and permanent clothes, they are easy to fluff.
Brightly colored clothes. Flamingos, bright green and indigo clothes usually fade more easily than other fabrics. It is best to wash it alone or try it once and then wash it with other clothes. To be on the safe side, first test whether it will fade in an inconspicuous place, and then pretreat it with detergent. Bright colors may fade over time.

"It's easier for me because I work at home and I can take care of it every day. I put my clothes in the washing machine in the morning and let it wash when I clean the room. Sometimes I let it wash itself when I'm on a business trip. If I go out, I never put my clothes in the dryer. Because once the rotation is stopped, the clothes will stay inside for a long time and will wrinkle. "

Wash away stains and dirty spots
Confirm the stain The more you know what a stain is, the more likely you are to handle it correctly. This means that the more likely you are to get rid of it, the less likely you are to make it more stubborn by adopting the wrong method. If you are not sure, soak in cold soapy water before washing.
Wash the stain immediately. The faster you process it, the easier it will be to delete it. Get into the habit of checking whether there are stains on wet clothes that have just been washed.

Once the stain is exposed to the air, the sugar will oxidize, leaving a visible stain, which will eventually turn yellow or brown. The stain will always exist, and will always exist.
