After wearing clothes for a long time, there will always be some unknown stains , and I don’t know when they got them. Even if they are washed frequently, they can’t be washed off. A good piece of clothing may fall out of favor because of this stain. Faced with such stubborn stains, is there any way to save them and restore their innocence?how to remove stains from clothes?
Three clues to distinguish the components of stains
To remove stubborn stains on clothes, you must first know the composition of the stains. It can be judged based on the following three clues:
1. Observe the location of the stain
Food stains usually appear on the front of clothes or the buttocks of pants; sweat stains usually appear on the neckline and cuffs; pants or skirts are easily stained with black motor oil when getting in and out of the car; cleaning agents or bleaching agents used after cleaning the kitchen or bathroom It may remain on the waist of clothes.
2. Smell the dirt
After the engine oil and general oil stains are dried, it is difficult to distinguish from the appearance, but the engine oil stains may smell rancid because of the relationship between the residual gasoline and the odor of fuel.
3. Check the color of the dirt
Generally speaking, if the color of the stain is brown, it usually contains protein content; if it is gray, it is usually a grease stain. Some clothes fade because they have been bleached, usually because of the use of chlorine-based bleach. There is no way to recover stains from bleach.
Some stains are difficult to identify from the color. For example, red-brown stains may be tea, coffee, caramel, markers, rust, or other “culprits.”
Nine practical decontamination cleaners
The first point in removing stains is to avoid damaging clothes as much as possible, and use the least destructive method to deal with difficult stains. In addition, different cleaning methods are required for clothes of different materials and different stains.
If the cleaning method is improper, the stains may become more serious. Here are several environmentally friendly and practical decontamination cleaners:
● White Vinegar
White vinegar can dissolve tannic acid stains, such as tea, coffee, fruit juice, etc. It can also eliminate odor and make clothes soft. It is a useful natural detergent and softener.
● Baking Soda
It can remove oil stains and eliminate peculiar smells. It is a very widely used household cleaner.
● Coarse salt
Salt has the functions of sterilization, disinfection, and bleaching, and when combined with lemon juice, it can remove rust and dirt.
General cleaning agents contain surfactants, which utilize the hydrophilicity and lipophilicity of the surfactants to remove dirt from clothing fibers, and achieve the purpose of cleaning based on physical principles. In recent years, enzyme cleaners with added biological enzymes have become popular.
They use chemical reaction mechanisms to decompose and neutralize difficult-to-wash components such as protein, lipids, cellulose, starch, etc., and can be removed. Generally, only surfactants are included.
The stubborn dirt cannot be washed off by the cleansing agent. Since there are different enzymes for different clothes and dirt, you should pay attention to the objects suitable for cleaning when buying such products. Enzyme cleaners are more expensive, but have less impact on health and the environment.
● Concentration of 2% hydrogen peroxide
The mildest bleaching agent needs to be soaked in water.
● Industrial alcohol
Colorless industrial alcohol is a common stain remover, used to remove oily ink such as ball pens, strange pens, oily markers and other difficult stains.
● Oxygen bleach
Mild bleach can be used to remove stains and whiten clothes. It is suitable for almost all washable white and colorful clothes. Oxygen-based bleach is slower than chlorine-based bleach, is less corrosive, and does not damage clothes. However, it is still not advisable to use too much, and do not mix it with cleaning agents such as hydrochloric acid, acetic acid, and chlorine-based bleach, to avoid chemical changes that may cause danger.
People who are allergic to bleach or do not like the smell of bleach can use sodium percarbonate instead. Sodium percarbonate is a strong base and has similar decontamination properties to baking soda . It is also a very environmentally friendly oxygen-based bleach. Sodium percarbonate is suitable for washing clothes made of vegetable fibers (such as cotton, hemp) or synthetic fibers (such as nylon, polyester fibers). It cannot be used to clean animal fibers (such as silk, wool) and regenerated fibers (such as rayon). Clothing.
● Chlorine bleach
It has a strong bleaching effect and can be disinfected and deodorized. To kill most types of bacteria, viruses and molds. If you want to use chlorine-based bleach, you must clean the working environment so as not to contaminate the next batch of laundry; when washing clothes with a washing machine , pay attention to whether the function of the bleach distribution box is normal, and when you go to the laundromat to do laundry Even more so.
● Staining oil
Used to remove black oil stains. When cleaning clothes stains, a cloth or paper towel should be placed on the back to prevent the dirt from penetrating. Because scouring oil is a volatile substance, please use it in a ventilated open space.
3 steps to remove stubborn stains on clothes
Clean clothes stubborn stains, you must throw in the washing machine before, do first the following pre-wash stain removal action:
1. Soak in water

It is best not to use a clothes dryer for stained clothes, because high-temperature drying will make stains more difficult to remove.
3. Use bleach
If the above methods still fail to remove the stains, use an oxygen-based bleaching agent. Soak in warm water (60 degrees Celsius) and oxygen-based bleach for about 40 minutes (depending on the severity of the stain), and then wash the clothes according to the general procedure. This method is suitable for most clothes that can be washed, including white clothes. However, silk, wool, and leather or metal trims cannot be used.
If sodium percarbonate is used, it needs to be dissolved in warm water above 40 degrees Celsius. After soaking, follow the normal washing procedure.
Try to avoid using chlorine bleach to remove stains (even white cotton clothes). If the stain is actually rust, chlorine-based bleach may allow it to permanently set on the clothes.
