Why care for fabrics, and reading care labels
Clothes get dirty from sweat, dust and food. Care keeps them clean, hygienic, good-looking and long-lasting, and saves money.
A care label is a small tag sewn inside the garment. It uses picture symbols that are the same in many countries:
- Wash tub: can be washed in water. A number (30, 40, 60) is the highest water temperature in ยฐC. A hand in the tub means hand wash only.
- Triangle: bleach. Crossed out = do not bleach.
- Iron: one dot = cool (synthetics, silk), two dots = warm (wool, polyester), three dots = hot (cotton, linen).
- Circle: dry clean. Letters inside tell the cleaner which solvent to use.
- Square: drying. A circle inside the square = tumble dryer allowed.
A cross (X) on any symbol means "do not". Always read the label before the first wash.
Mending: repair before you wash
Mending means repairing small damage before it grows. Washing makes a small tear bigger, so mend first.
- Loose button or hook: sew it back firmly.
- Open seam: run a back stitch along the old seam line.
- Small hole (knitted socks, sweaters): darning, weaving thread across the hole in rows like a tiny fabric.
- Big tear or hole: patching, sewing a piece of matching cloth behind or over it.
- Hem down: hem stitch it back.
Stain removal
A stain is an unwanted mark that normal washing does not remove. Golden rules:
- Act fast: fresh stains come out more easily.
- Identify the stain and the fabric first.
- Test the remover on a hidden part (inside seam).
- Put a pad under the stain and dab from the edge to the centre so it does not spread.
- Use cold water for protein stains (blood, egg, milk): hot water cooks the protein into the fibre.
- Rinse well after every remover.
Kinds of stains and removers
- Animal (protein): blood, egg, milk: soak in cold salt water, then wash with detergent.
- Vegetable: tea, coffee, fruit, curry (turmeric): pour hot water from a height (white cotton), or lemon juice / mild bleach; sunlight fades turmeric.
- Grease and oil: ghee, oil, lipstick: absorb with powder (talc, chalk), then detergent or a grease solvent.
- Mineral: rust, ink: lemon juice and salt or oxalic acid (handle with care) for rust.
- Dyes: colour bleeding: soak in mild bleach for whites only.
Removers work in three ways: absorbents (talc, chalk, blotting paper soak it up), solvents (water, spirit, acetone dissolve it) and bleaches (oxidising: hydrogen peroxide, sodium hypochlorite; reducing: sodium hydrosulphite) remove colour. Never use chlorine bleach on wool or silk.
Soaps and detergents
Water alone cannot remove oily dirt, because oil and water do not mix. A cleaning molecule has two ends: a water-loving head and an oil-loving tail. The tails dig into the grease, the heads face the water, and the grease is wrapped in a tiny ball (a micelle) that rinses away.
- Soap: made from fats or oils with an alkali. Gentle and biodegradable, but in hard water it forms a sticky scum and wastes soap.
- Synthetic detergent: made from petroleum chemicals. Works well even in hard and cold water. Some have phosphates or enzymes; some types break down slowly and can harm rivers.
Forms: bars, flakes, powders, liquids. Mild (neutral) detergents suit wool and silk; strong (alkaline) ones suit cotton and linen.
Washing methods
Steps for any wash: sort (whites, colours, delicates), pre-soak heavy dirt, wash, rinse until no soap is left, then dry.
- Friction: rubbing by hand or with a brush, scrubbing on a board. For strong cotton and linen only.
- Kneading and squeezing: gentle pressing in soapy water. For wool, silk and delicate fabrics; no twisting.
- Suction: a suction washer moved up and down pulls water through the cloth. Good for bulky items like towels.
- Machine washing: a drum turns the clothes in water; programmes change speed and temperature.
Drying: whites in sunlight (natural bleaching), coloured clothes inside-out in shade, woollens flat on a towel so they do not stretch.
Finishing: blue and starch
Blue (laundry blue / whitener): old white cotton turns slightly yellow. A very little blue colour cancels the yellow, so the cloth looks whiter. Use a few drops in the last rinse and mix well; too much leaves blue patches. Modern detergents often contain optical brighteners that glow blue-white in daylight.
Starch (stiffening): starch fills the spaces between cotton fibres and dries to a crisp finish. It keeps clothes fresh-looking, makes dirt wash off more easily next time, and makes ironing smoother. Rice water, arrowroot, maize starch or gum arabic (for silk) are used. Starch cotton and linen; do not starch wool or synthetics.
Ironing and pressing
Heat + moisture + pressure relax fibres and flatten wrinkles.
- Ironing: sliding the iron along the cloth (cotton, linen).
- Pressing: lifting and pressing down without sliding, often through a damp cloth (wool, to avoid shine).
Match the heat to the fibre: cotton and linen hot, wool and silk medium, nylon, polyester and acrylic cool (they can melt). Iron along the grain, iron dark colours inside-out, and finish thick parts (collar, cuffs) first. A steam iron adds moisture automatically.
Dry cleaning
Dry cleaning cleans clothes in a liquid solvent instead of water, so fibres do not shrink, felt or lose shape. It suits wool suits, silk saris, heavy embroidery and some coats. The professional solvent dissolves grease, the clothes are spun, then dried and pressed. At home, small grease spots can be cleaned with a little absorbent powder or a mild spirit, but solvents are flammable, so use them in open air and away from flames.
Storage
Store clothes clean and completely dry: dirt and sweat attract insects, and damp causes mildew (fungus spots and smell).
- Fold heavy knits; hang shirts, trousers and dresses on shaped hangers.
- Store silk and wool with natural repellents (dried neem leaves, cedar) or naphthalene balls kept in a cloth so they do not touch the fabric.
- Keep a dry, airy, dark place; sun-air the clothes now and then.
- Wrap expensive silks in soft cotton cloth, not plastic, and refold along new lines to avoid permanent creases.
Try it at home
Take two old white cotton rags. Put a drop of tea on each. Treat one at once with cold water and a little detergent; leave the other for two days, then treat it the same way. Compare. Then find the care label on your school shirt and write what each symbol means.
Key formulas and definitions
- Care order: label โ mend โ stain โ wash โ blue/starch โ iron โ store
- Iron dots: 1 = cool (~110 ยฐC), 2 = warm (~150 ยฐC), 3 = hot (~200 ยฐC)
- Protein stains: cold water first
- Grease: absorbent โ solvent โ detergent
- Wool and silk: mild detergent, kneading and squeezing, dry flat in shade
- Soap + hard water โ scum; detergent works in hard water
Worked examples
1. A care label shows a tub with 30, a crossed triangle and an iron with one dot. How do you care for this garment?
Wash in water no hotter than 30 ยฐC, do not use bleach, and iron on the coolest setting. It is probably a synthetic or delicate fabric.
2. Fresh blood falls on a white cotton handkerchief. What do you do?
Rinse at once in cold water (hot water would set the protein). Soak in cold salt water, then wash with detergent. If a mark remains, dab with a little hydrogen peroxide and rinse.
3. Your woollen sweater needs washing. Choose the method.
Use lukewarm water and a mild detergent, wash by kneading and squeezing (no rubbing or twisting), rinse in water of the same temperature, roll in a towel to remove water, and dry flat in the shade.
4. Why does an old white cotton kurta look whiter after a little blue in the last rinse?
Old cotton turns slightly yellow. Blue is the opposite colour to yellow, so a tiny amount cancels the yellow tint and the eye sees white.
Common mistakes
- Using hot water on blood, egg or milk stains: it sets them permanently.
- Rubbing a stain hard from the middle: it spreads and damages fibres. Dab from the edge inwards.
- Using chlorine bleach on wool or silk: it destroys these protein fibres.
- Storing clothes slightly damp or unwashed: this invites mildew and insects.
