Methods for removing glue and adhesive pigment stains

1. Removal of universal glue stains
If clothes are stained with universal glue, acetone or banana oil can be dripped onto the glue stain, and a brush should be used
continuously to scrub repeatedly until the glue softens and detaches from the fabric, then rinse with clean water. If not successful the first time, repeat several times until clean. Do not use this method on fabrics containing acetate fibers to avoid damage.
2. Removal of white latex glue stains
White latex is a synthetic resin, a polyvinyl acetate emulsion. It adheres firmly to most cellulose-based materials except for nylon satin. It also dissolves in various solutions. Using this property, white latex stains on clothes can be soaked in 60°C white liquor or an 8:2 mixture of 95% alcohol and water for about half an hour, then rubbed with water until clean, and finally rinsed with clean water.
3. Removal of chewing gum stains
If clothes are stained with chewing gum, first remove the sticky surface with raw egg white, then wipe off the loose residue one by one, finally wash in soapy water and rinse with clean water. For non-washable fabrics, carbon tetrachloride can be applied to remove residual stains.
4. Removal of glue stains
If clothes are stained with glue, soak the stained area in warm water. When the stain dissolves, rub by hand until the stain is completely removed, then wash once with warm detergent solution and rinse with clean water.
5. Removal of watercolor stains
Watercolors used in painting contain water-soluble glue to enhance color fastness. When clothes are stained with watercolor, first dissolve and remove the glue with hot water, then use detergent or mild ammonia water to decolorize, and finally rinse with clean water. White clothes can be decolorized with hydrogen peroxide.

Methods for cleaning blood stains on clothes

1. Fresh blood stains: Fresh blood on any fabric can be removed by washing with water. First wash with clean cold water, then with soapy water or detergent. Using hot water will not remove the stain and may leave permanent marks.
2. Older blood stains on clothes: Use a mixture of 2 parts borax, 1 part 10% ammonia water, and 20 parts water to wipe the stain. After removal, rinse with clean water. Old blood stains can also be washed with lemon juice and salt water.
3. Blood stains on delicate dyed silk and wool garments: Make a paste from starch and water, apply it to the blood stain and let it dry. Once dry, scrape off the starch, wash with soapy water, rinse with clean water, and finally wash with a vinegar solution made from 15g vinegar per liter of water for good results.
4. Blood stains on white clothes can be removed by soaking in a heated solution of 1 part sodium thiosulfate diluted with 50 parts water at 35°C until the blood color disappears, then wash with water. For older, firmly adhered blood stains on white clothes, use a color remover. Alternatively, soak overnight in a 5% baking soda or ammonia solution, then wet the stain with a bleach powder solution (1 part bleach powder to 10 parts water) and rinse thoroughly. Blood stains on white fabrics can also be removed by soaking in a 3% vinegar solution for 12 hours before rinsing, which is also effective.

Cleaning soy sauce, soup, seasoning sauce, and milk stains on clothes

Methods for removing grease stains
　　
Grease stains, commonly known as oil stains, are water-insoluble stains. These stains should be removed from clothes using organic solvents such as gasoline, trichloroethylene, tetrachloroethylene, alcohol, acetone, xylene, banana oil, turpentine, benzene, etc., by wiping or brushing. Additionally, other effective methods can also be used for removal.
1. Removal of animal and vegetable oil stains
Animal and vegetable oil stains are common on clothing and are polar liquid stains. These stains should be removed by wiping or brushing with organic solvents such as gasoline or tetrachloroethylene. When brushing, use a towel or cotton cloth to promptly absorb the dissolved stain solution to prevent residue on the fabric surface after solvent evaporation, which can cause marks. If marks appear, repeat wiping or expand the brushing area to remove them. Alternatively, apply water to the stained area and use a high-pressure spray to remove it.
2. Removal of pine resin stains
When handling pine wood, clothes can easily get pine resin stains, which should be removed promptly. Based on the principle that pine resin dissolves in alcohol, apply alcohol or a mixture of alcohol and turpentine to the stain. After the resin softens and dissolves, wipe and absorb it with a wet towel. If marks remain, wipe again with gasoline repeatedly until clean.
3. Removal of tung oil stains
Tung oil is a viscous vegetable oil that is not easy to dry and is difficult to remove from clothes. Use gasoline or kerosene to brush and dissolve the tung oil, then remove it. Afterwards, use alcohol soap to remove any remaining marks. It is best to wash the treated clothes again with detergent to thoroughly eliminate traces.
4. Removal of butter stains
Butter is a viscous animal fat that can be wiped with solvents such as toluene or carbon tetrachloride. Remaining marks can be removed with a mixture of alcohol and ammonia solution or with alcohol soap.
5. Removal of curry oil stains

For dark-colored machine oil stains, wash with high-quality gasoline, then absorb with blotting paper or cloth by ironing, and finally rinse with warm water.
7. Removal of candle wax stains
Candle wax on clothes cannot be removed by washing alone. First, rub off the wax on the surface by hand, then place blotting paper or highly absorbent paper above and below the stain and iron. The heat melts the wax, which is absorbed by the paper. If not clean after one time, repeat several times until the candle wax stain is completely removed.
8. Removal of chimney oil stains
If chimney oil drips on clothes, immediately soak the clothes in water to prevent oxidation with air. Then sprinkle crystalline oxalic acid powder on the stain, rub repeatedly until mostly removed, then wash with detergent and rinse with clean water.
9. Removal of kerosene stains
Kerosene stains are non-polar liquid stains. When kerosene gets on clothes, if not removed promptly, it will leave yellow marks, especially obvious on white fabrics. To remove kerosene stains, you can sprinkle chalk powder or magnesium oxide powder on the stain, and after a few days, remove it with clean powder. Through the adsorption effect of the powder, the kerosene stain will disappear without leaving a trace.
10. Removal of smoke black spots
Red or purple velvet clothes often turn dull gray after being smoked, and sometimes black spots appear. This is due to changes caused by the dye reacting with carbon dioxide. In such cases, simply spray with alkaline water once to restore the original color.
11. Removal of cigarette oil stains
If clothes are stained with cigarette oil, you can repeatedly rub with 1%~2% potassium permanganate aqueous solution, then repeatedly rub with 3% hydrogen peroxide, and finally rinse with clean water. 12.

5. Removal of purple medicine stains
The main component of purple medicine is extracted from gentian, so purple medicine is also called gentian violet. It is a commonly used external medicine. When it stains clothes, it shows a very conspicuous bluish-purple color.
The removal method is: soak the clothes in water, wring slightly, then use a cotton swab dipped in 20% oxalic acid aqueous solution to apply the stain from inside out. After soaking briefly, rinse and rub repeatedly with clean water, and the stain can be removed. Additionally, for some white fabrics stained with purple medicine, you can first remove the floating color with solvent alcohol, then bleach with oxidants such as sodium hypochlorite or hydrogen peroxide solution. After washing with water, the desired effect can be achieved.
6. Removal of yellow medicine stains
Light-colored, especially white clothes stained with yellow medicine, are relatively troublesome to remove. First, drop acetic acid on the stain. If the effect is not obvious, wash in alcohol.
If it still cannot be completely removed, select a suitable oxidant according to the fabric fiber properties for stain removal or bleaching.
7. Removal of iodine tincture stains
If clothes are stained with iodine tincture, you can choose alcohol or potassium iodide to remove it. Add 5~7 grams of potassium iodide to 100 ml of water.

10. Removal of rust stains
Rust stains on clothes can be soaked in 1% warm oxalic acid aqueous solution, then rinsed with clean water. You can also wipe the stain with 15% acetic acid aqueous solution or soak the stained part in the solution, then rinse with clean water the next day. You can also moisten the stain with 10% citric acid solution or 10% oxalic acid solution, then soak in concentrated salt water, and wash and rinse with clean water the next day. For white pure cotton or cotton blend fabrics stained with rust, place a grain of oxalic acid on the stain, moisten with warm water, gently rub, then rinse with clean water. During the operation, to prevent oxalic acid from corroding the fabric, the action should be quick. You can also drop fresh lemon juice on the rust stain, rub with your hand repeatedly until the rust stain is removed, then wash with detergent and rinse with clean water.
11. Removal of verdigris

Note
Do not soak in colored rice washing water to prevent staining.
Yellowed silk clothing can also be bleached with lemon juice or dilute citric acid, both of which can remove yellow stains. Finally, rinse thoroughly with clean water.
The nemesis of clothing stains, a good helper for laundry!!

Cleaning unknown stains on clothing

In daily life, clothing often has some unknown stains. When discovered, one may not remember their origin, so it is often ineffective to treat specifically. Therefore, using more general cleaning methods is more effective.
1. Stains on white clothing
Use a mixture of 4 parts 10% ammonia, 1 part soda (sodium carbonate), 2 parts high-quality white soap, 4 parts alcohol, and 100 parts water. Moisten the stain with this mixture using a cloth, then wipe until the stain is removed, and rinse thoroughly with clean water.
2. Stains on any fabric
Use a mixture of 5 parts 10% ammonia, 3 parts acetone, and 20 parts alcohol soap solution to wipe. Alternatively, use a mixture of 1 part 90% alcohol, 1 part ether, and 8 parts pure turpentine to wipe.


Cleaning and care of T-shirts
 
A good T-shirt must be made of soft and elastic material, breathable and cool to wear. When washing, turn the entire T-shirt inside out and avoid rubbing the patterned side. Hand wash as much as possible and avoid using a dryer. When hanging, do not pull the collar to prevent deformation. Remember to carefully wash and care for clothes during seasonal changes. Understanding the fabric before cleaning and ironing will prevent damage to your beloved clothes.

Cotton fabrics
1. Vinegar can corrode cotton fabrics, so when acidic substances like fruit juice stain cotton, it is best to treat immediately with clean water to prevent the stain from setting and becoming difficult to remove.
2. Alkali does not easily damage cotton fabrics, so weakly alkaline detergents with strong cleaning power can be used.
3. Sunlight causes oxidation in cotton fabrics, making white cotton yellow and brittle. Some cotton dyes are especially sensitive to sunlight and may fade easily when overexposed, especially blue, purple, and pink colors. It is advisable to turn clothes inside out when drying.
4. Light-colored cotton clothes gradually yellow after repeated washing. Boil them in water with detergent for 20–30 minutes, then rub with clean water to restore their original appearance.
5. The ironing temperature for cotton fabrics should be around 180 degrees Celsius. Since cotton material is not easy to iron flat when completely dry, it is best to spray some water evenly to allow moisture to penetrate before ironing cotton fabrics, which can achieve better results with less effort.

Synthetic fibers
Synthetic fibers such as nylon NYLON, polyester POLYESTER, acrylic ACRYLIC, and various fibers have different characteristics, so their cleaning and maintenance methods also vary.
1. Nylon fabrics do not fade easily but are prone to staining. When washing, be sure to separate them from other dark-colored clothes to avoid staining.
2. Use neutral detergent to wash nylon clothes, avoid hot water. Nylon clothes dry quickly after washing and do not require tumble drying.
3. Iron nylon clothes at low temperature, about below 140 degrees Celsius.

Tips to prevent clothes from fading in summer:
(1) Reverse sun-drying method: When drying clothes, turn them inside out, with the inside facing the sun and the outside in the shade.
(2) Additives: When washing synthetic fiber clothes, add some salt to the water; for washing high-grade fabrics, a small amount of alum can be added to the water to prevent or reduce fading.
(3) Acid wash method: When washing colored fabrics, add 1 to 2 tablespoons of vinegar to the detergent to prevent fading.

Key points for drying clothes
(1) Clothes should not be exposed to direct sunlight. Dry them in a cool, ventilated place until half dry, then place them under weaker sunlight to protect the color and lifespan of the clothes.
(2) Pay attention to wind direction when drying clothes. Due to severe urban air pollution in recent years, especially downwind near factory areas, the air often contains a large amount of dust. Ignoring this can easily cause clothes to get dusty, affecting their appearance.
(3) Do not wring clothes too dry when drying. Dry them with some water left and use your hands to smooth the collar, cuffs, and other parts. This will keep the clothes flat and wrinkle-free after drying.

Storage methods and ironing techniques
(1) Storage methods
Natural fiber and synthetic fiber clothes should be hung for storage.
To prevent moth damage, use camphor balls. Camphor balls should be wrapped in paper bags and kept separate from clothes to avoid chemical reactions.
(2) Ironing techniques
A: Preparations before ironing: (Irons are divided into upright steam irons and household irons)
1) First, place the ironing board on a flat surface.
2) Check if the ironing board has a heat insulation cover.
3) Check if the iron temperature is suitable for the fabric of the garment (refer to the washing label before ironing).
4) Clearly understand which temperature is suitable for the garment; most clothes can use steam, but steam is not suitable
for parts with adhesive patches.
5) For clothes that are reflective (mirror-like), use an iron heat insulation cover (or cover with cloth) to protect the fibers from damage.
6) The iron's water reservoir should be moderate, not too full, to avoid excess water leaking and causing water stains on clothes.
7) After filling the iron with water, do not lay it flat; tilt it slightly upwards to prevent water leakage.
8) Adjust the iron temperature gradually from low to high until it reaches the suitable temperature for the garment.
Note: Do not iron adhesive parts neatly, such as the front lapel and collar of suits.
B: Common ironing mistakes:
1) The collar line of the shirt is not ironed accurately.
2) The lapel line of outerwear is not properly pressed.
3) Wrinkles appear on the top of the sleeves after hanging, mainly because suitable sleeve ironing tools were not used.
4) The crease of the pants is not centered (not aligned during ironing).
C: Post-ironing precautions:
1) Empty all water from the iron to avoid sediment buildup from long-term water storage.
2) Remove the iron heat insulation cover.
D: How to remedy clothes damaged by ironing
1) If the clothes have slight shiny spots from ironing (common in dark clothes), use steam to restore them. If the condition is severe, apply a small amount of talcum powder on the surface, wait five minutes, then set the iron to steam temperature and iron over the clothes with a cloth in between to restore the original appearance.
(Note: When using steam, do not let the iron directly touch the clothes; keep a slight distance and spray steam on the shiny spots to restore them.)
------For minor scorching on cotton fabrics, sprinkle some fine salt and gently rub.
------Silk: Use a small amount of baking soda mixed with water into a thin paste, apply on the scorch mark to make it disappear.
