Three Days, ₹800 and Three Stains: A Clothing Judgement Call
Ravi, a Class XI student in Coimbatore, is packing for a three-day NSS camp followed immediately by a family wedding. He has ₹800. He must carry a white cotton uniform shirt with a blue ballpoint ink line on the pocket and a yellowed collar, a grey polyester-blend uniform trouser with a grease patch from his cycle chain, and a cotton towel stained with sambar. For the wedding he can buy one shirt: 100% cotton at ₹650 or a polyester 'wrinkle-free' shirt at ₹420. Coimbatore in April is 36 °C with high humidity; the camp offers only bucket washing and line drying in the sun, with no ironing. His mother's silk saree also has a small curry stain, and she plans to wash it in hot water with detergent and bleach.
1. Match each stain to the right agent and method, and explain why the mother's plan for the silk saree is dangerous.

Order of work: deal with grease first (it spreads), then protein/food stains, then ink, and wash the garment last. Always test any agent on an inside hem first.
Grease patch (cycle chain) on polyester blend
- Do not rub. Blot the fresh oil with blotting paper or dust with talcum/chalk and brush off.
- Work a little detergent or dish-soap into the spot with fingers, leave 10 minutes, wash in the hottest water the label allows (polyester tolerates warm water well).
- Rubbing only drives the oil along the fibre and leaves a grey halo.
Ink line on white cotton
- Dab with methylated spirit or rubbing alcohol on cotton wool, working from the outside of the stain inward so it does not spread; rinse between dabs. Soaking in sour curd or lemon juice and salt is the cheap alternative.
- The shirt is white, so a dilute chlorine bleach is permissible as a last resort; it is not permissible on anything coloured.
Yellowed collar on white cotton
- This is oxidised body oil and sweat. Apply a detergent paste, leave 20 minutes, wash, then dry in direct sun - sunlight is a natural brightener for white cotton.
Sambar on the cotton towel
- Blot the oil, then wash with soap and lemon juice and dry in the sun; turmeric-based colour fades in sunlight.
Why the silk saree plan is wrong: silk is a protein fibre. Hot water plus a strong alkaline detergent plus bleach (an oxidising agent) attacks the protein, dulls the lustre, yellows white silk and can shred the fibre; heat also sets the curry stain and may shrink the fabric. Correct method: cold water, mild soap or shampoo, no bleach, no wringing, dry in shade, or dry-clean if the saree is valuable.
2. Which shirt should Ravi buy with his ₹800? Justify by comparing the two fibres against the actual conditions.
Read the worked answer
Set the criteria from the situation, not from habit: 36 °C with high humidity, three days of physical camp work, only bucket washing, line drying in the sun, no iron, and a wedding the next day.
Cotton
- Absorbs moisture well and lets air through, so sweat evaporates and he stays comfortable in humid heat; it does not cling or smell as quickly.
- Weaknesses here: it creases badly and needs ironing, takes longer to dry, and the wedding shirt must look presentable.
- ₹650 leaves ₹150 of his ₹800 - enough for a wash and a paid iron at the camp town, but nothing else.
Polyester
- Hydrophobic: it does not absorb sweat, so in high humidity it feels clammy against the skin, can trap odour and build static.
- Strengths: it dries fast on a line, resists creasing, needs no iron and costs ₹420, leaving ₹380 for soap, travel and incidentals.
Defensible decisions
- If the wedding is indoors and he can get the shirt pressed once, buy cotton (₹650): comfort across three days of physical work outweighs the creasing, and the ₹150 pays for ironing.
- If no iron will be available at all and appearance at the wedding is the deciding factor, buy polyester (₹420) and manage the clamminess with a cotton vest underneath.
The examiner is looking for the reasoning: fibre properties matched to temperature, humidity, washing and ironing constraints and the budget - not a fixed 'cotton is best' slogan.
3. Write a three-day washing and care plan Ravi can actually follow at the camp.

Day 0, before leaving
- Pre-treat the ink, grease and collar stains as described, wash and dry everything, and check that all buttons are secure.
- Pack a small bar of detergent, a stain stick or soap, a few clothespins and a plastic bag for wet clothes.
Daily routine (bucket method)
- Sort: whites and light colours separately from the grey trouser; never wash white cotton with the polyester grey, which can bleed dye.
- Soak the uniform for 10–15 minutes in warm soapy water, then squeeze gently - no hard scrubbing on the collar, which frays the fabric.
- Rinse twice until the water runs clear; detergent left in the fibre attracts dirt and irritates skin in heat.
- Dry: white cotton in direct sun (brightens it and kills odour bacteria); the polyester trouser and any coloured item in shade to prevent fading and yellowing from over-heating.
- Polyester needs no iron - hang it straight from the rinse, smooth by hand and it dries almost crease-free. Cotton gets a shake and a straight hang, then a press before the wedding.
Care-label rule: before any hot wash, bleach or iron, read the label. White cotton tolerates heat; polyester must be ironed cool or it glazes and shines; silk is never bleached, never boiled and never wrung. Teaching Ravi to read the five symbols - wash, bleach, iron, dry-clean, tumble - is the transferable skill the question is testing.
