The seat and elbows of my suit or uniform have gone shiny. Can it be fixed? Prevented?

This answer is a draft. It stays unpublished until legal review and source verification are complete.

The answerShine is the nap of the fabric (the fibre ends) crushed flat by friction. In the early to middle stages, steaming (hold the iron above the cloth and use steam only, or use a garment steamer) lifts the fibres, and a clothes brush stands the nap back up, so the shine fades. The traditional method is a mist of diluted vinegar (1 part water to 1–2 parts vinegar), then brush, then steam; the acid is generally described as helping the fibres stand up. Once the fibres themselves have worn thin (the cloth is see-through, the gloss is fixed all over), it will not come back; buying an extra pair of trousers, or a dry cleaner's "shine removal" service, gives temporary improvement at best. To prevent it: do not wear the same suit on consecutive days, sweep your jacket tails aside before sitting, put a cushion or cloth on the chair seat, and brush and hang your trousers after every wear.

Sit at a desk all day and the seat, elbows and knees of a suit start to shine. This "shine" (テカリ, tekari) is the surface nap pressed flat so that it reflects light, and for Japan's office suits and school uniforms it is an unavoidable nuisance. Here is what can be reversed, and how to slow it down.

Stages of shine and what to do

StageConditionWhat to doReversible?
EarlyA slight shine at some angles. The cloth is still thickSteam (hold above the cloth, steam only) → clothes brush to lift the napYes
MiddleAlways shiny. Smooth to the touchMist with diluted vinegar (1 water : 1–2 vinegar) → brush → steam. Or ammonia water (a few drops in water). Light ironing on low with a pressing cloth can make it worse, so steam onlyLargely
LateThe cloth is thin and see-through, and looks fadedThe fibres are worn away and will not recover. A dry cleaner's "shine removal" (テカリ直し) (a nap-raising process, ¥1,000–3,000) for a temporary fixNo

Preventing it

MeasureDetails
Do not wear on consecutive daysRotate 2–3 suits; rest a suit for 1–2 days after each wear. Wool fibres recover when rested
How you sitSweep the jacket tails aside before sitting; do not sit on them (shine and creasing on the back); pinch up the trouser knees slightly as you sit; no wallet or phone in the back pocket (friction and distortion)
ChairSynthetic leather and hard seats cause more friction. Use a fabric cushion or seat cover. Same for car seats
Daily careClothes brush after coming home (along the nap); hang trousers on a trouser hanger; steam once a week
Fabric choiceAll-wool cloth recovers; polyester blends shine more easily. Tightly woven cloths (serge, gabardine) shine easily; flannel and tweed show it less
Two pairs of trousersTrousers wear out before the jacket. Buy a two-trouser suit, or from a shop that sells extra trousers in the same cloth
UniformsSchool uniforms (wool-polyester blends) shine especially easily. Keep a spare pair of trousers or skirt; brush after school. Iron on low with a pressing cloth
[Verify] Nap-raising with vinegar or ammonia is a method passed down in the dry-cleaning trade and in homes; its effect on cloth varies by fibre. Check against materials from the national federation of dry-cleaning associations (Zenkuren).

Misunderstanding 1|Shine is dirt, so washing will get rid of it

It is a physical state — flattened nap — and washing does not reverse it. Lift it with steam and a brush.

Misunderstanding 2|A good hard ironing makes shine disappear

Heat and pressure are the biggest cause of shine. Steam from above, then brush.

Misunderstanding 3|Wearing the same suit every day is fine

Daily wear robs the fibres of time to recover. Rotating 2–3 suits adds years to their life.

Misunderstanding 4|Late-stage shine can be fixed too

Once the fibres are worn thin it will not come back. The cleaner's process is temporary. Buy extra trousers.

Misunderstanding 5|Polyester blends are tougher, so they don't shine

In polyester blends the nap is set by heat, so they shine easily and recover poorly. All-wool cloth has more recovery.
